Prevalence of Dental Caries in Children Visiting a Dental College and Hospital in the United Arab Emirates: A Cross-sectional Study.

AIM: The purpose of this study was to examine the prevalence of dental caries in school children visiting a dental college and hospital and investigate the associated risk factors. MATERIALS AND METHODS: Eighty children were recruited in this study between the ages of 6-12 years. The caries prevalence of decayed, missing, filled teeth (DMFT) was recorded using an evaluation form. A structured questionnaire was used to understand the associated risk factors. RESULTS: The caries prevalence in the population was found to be at 91.25%. There was a strong negative correlation between age and dental caries and the results were statistically significant with p-value being less than 0.0001. The duration of bottle and breastfeeding, frequency of teeth brushing, adult supervision during brushing, consumption frequency of sweets, and the frequency or timing of children's dental visits were found to be positively associated with dental caries and these results were statistically significant with p-value being less than 0.05. CONCLUSION: A high prevalence of dental caries was observed among the population visiting the dental college and hospital. Encouraging dental health education, including promoting the significance of good oral hygiene practices, is crucial. CLINICAL SIGNIFICANCE: The study emphasizes the rising prevalence of dental caries and underscores the need for dental health education and the promotion of good oral hygiene practices to prevent complications and reduce their prevalence.

Knowledge and Practice of Immediate Dentures among the Dentists in Private Clinics in Khartoum State: A Descriptive Cross-sectional Study.

AIM OF THE STUDY: To assess the awareness and practice of Immediate Dentures among the dentists who work in the private clinics in Khartoum state, Sudan Materials and methods: A descriptive cross-sectional questionnaire-based study was conducted among the dental medical officers, registrars, specialists, and consultants who are working in private clinics and centers in Khartoum state and registered the private medical institutions in Sudan. The sample population was 664, using the stratified sampling technique and simple randomization within the stratum, 265 dentists were asked to participate in the study voluntarily A self-administered questionnaire consisted of 32 closed questions and 3 sections, section (1) involved the participant's data, section (2) contained the participant's knowledge, and section (3) the participant's practice was distributed. The participant's knowledge and practice scores were calculated as percentages achieved by dividing the number of accurate answers of the participants by the total number of questions and categorized as Good (66.6-100%), Average (33.3-66.6%), and Poor (less than 33.3%) Data was collected and analyzed using a statistical package of Social Science (SPSS) computer software version 22. Chi-square was used for statistical analysis Results: The response rate was 100%, with nearly equal distribution between males (135, 50.9%) and females (130, 49.1%). The age range is 24-39 years, with a mean of 31.65 ± 7.52 years. The majority of the participants (172, 64.9%) were freshly graduated and young practitioners, with the majority of them having experience ranging from 1 to 6 years. The result of the study revealed that 65.7% of the respondents have average knowledge about immediate denture while 8.7% expressed poor knowledge and only 25.7% had excellent knowledge On the other hand, the majority of the participants (200,75.5%) have never constructed an immediate denture, while only 21.1% have a history of constructing 1-5 immediate dentures, 3% constructed more than 5-10 immediate dentures and only 0.4% constructed more than 10 immediate dentures The lack of knowledge and experience was the main barrier preventing the use of immediate dentures, and the mainstream of the participants (118, 44.5%), evaluated their knowledge about the immediate denture as poor Using the Chi-square test, the correlation between the participants' knowledge and their gender, years of experience, and qualification was found not significant (p -values of 0.46, 027, and 0.66, respectively) while a significant correlation was found between the participants' self-evaluation of their knowledge and their knowledge score with a p-value of 0.000* Conclusion: Within the limitations of this study, the dental practitioners have average knowledge about the immediate denture, but the practice of the immediate denture is still very limited and requires enhancement Clinical significance: Immediate dentures have a significant role in maintaining the patient's esthetics, phonetics, masticatory efficiency, self-esteem, and quality of life. Hence, the knowledge and practice of the different dentists about the immediate denture are of great importance to improve the standard of care provided for the patient Keywords: Dentists, Immediate denture, Knowledge, Practice.

Does the Protrusion of Corticobasal Implants in the Maxillary Sinuses Affect Sinus Health? A Retrospective Study.

AIM: The aim of this retrospective study is to investigate the effect of corticobasal implant penetration in the nasal and maxillary sinuses on sinus health and implant survival rate in cases of severely atrophid ridges. MATERIALS AND METHODS: This retrospective study was conducted on thirty patients with 172 implants who underwent corticobasal implant treatment between 2014 and 2018. Implants were divided into two groups according to the penetration depths (Group A, <4 mm; Group B, 4 mm). Inclusion criteria for the study included: (A) patients with severe maxillary ridge resorption with an immediately loaded corticobasal implant-supported prosthesis that showed implant protrusion inside the maxillary sinus on cone-beam computed tomography (CBCT); and (B) patients with a preoperative and postoperative follow-up CBCT scan using the same standard technique and machine. (C) Patients without any history of sinusitis before implant insertion patients who fulfilled the inclusion criteria were recalled for follow-up. The presence of sinus complications was clinically assessed according to the clinical practice guidelines for adult sinusitis of the American Academy of Otolaryngology-Head and Neck Surgery and Radiologically using CBCT. Moreover, patient satisfaction was evaluated using yes-or-no questions. The result was statistically analyzed using Fisher's Exact test. RESULTS: Despite the differences in implant penetration depths, no clinical signs of sinusitis were evident in any patient. One patient presented with transient epistaxis after the surgery, and 2 patients with nine implants revealed nonsignificant thickening of the sinus membrane radiologically (p = 0.055). All implants showed optimum bone-implant contact with a 100% survival rate. A significant relationship was reported between the thickness of the membrane and the patient's gender, hypertension, and smoking habits. (p = 0.001*, p = 0.002*, and p = 0.034*, respectively). CONCLUSION: Penetration of corticobasal implants in the maxillary sinus did not compromise the health of the maxillary sinus or implant survival rate. CLINICAL SIGNIFICANCE: Limited posterior maxillary bony support and maxillary sinus pneumatization present challenges in implant dentistry and increase the possibility of implant protrusion inside the maxillary and nasal cavities. Hence, studying the effect of this protrusion on the maxillary sinuses' health and implant survival is highly significant.

Knowledge and Practice of Radiation Stents for Oral Cancer Patients among the Sudanese's Maxillofacial Surgeons, Prosthodontists, Oncologists, and Radiotherapists.

AIM: To assess the knowledge and practice of radiation stents for oral cancer patients among the Sudanese's maxillofacial surgeons, prosthodontists, oncologists, and radiotherapists in Khartoum state. MATERIALS AND METHODS: A self-administered questionnaire composed of three sections, including the participant's sociodemographic, knowledge, and practice data, was conducted and distributed among the specialists and Registrars of maxillofacial surgery, prosthodontics, oncology, and radiotherapy who were working at the Khartoum Teaching Dental Hospital, the Faculty of Dentistry (University of Khartoum), and the Khartoum Oncology Hospital, respectively, during the study's duration. A cluster sampling technique was used, and within the cluster group, simple randomization was used. The sample size was 137 participants. The participant's knowledge and practice scores were calculated as percentages achieved by dividing the numbers of the accurate answers of the participants by the total number of questions and categorized as good (66.6%-100%), average (33.3%-66.6%), and poor (less than 33.3%). RESULT: The response rate was 80%. Forty five (40.9%) of the respondents were males, and 65 (59.1%) were females. The high-frequency age-group was 30-40 years (59 subjects, 53.6%). Thirty-eight participants (75.5%) were unfamiliar with the radiation stent. The overall knowledge score was poor, with a significant difference between the different groups (p = 0.0001*). Only the prosthodontists reported a good level of knowledge about the radiation stent (73%), while the oncologists and the radiologists showed a zero level of knowledge. Despite this, the practice score of the radiation stent was poor among all groups. The level of knowledge regarding the complications of radiation and the different protective measures among the maxillofacial surgeons, oncologists, and radiotherapists was 55%, 60%, and 50%, respectively, while the prosthodontists reported 70%. Only 27 (24.5%) participants reported a multidisciplinary treatment approach. At the same time, the majority, 59.1%, declared that they do not follow a formal clinical guideline and/or protocol for dental treatment in oral cancer patients. The lack of knowledge and communication between the different health providers were the main barriers preventing the use of radiation stents. CONCLUSION: The knowledge and practice of the radiation stent were poor. A highlighted need was strengthened to improve the training and communication among the multidisciplinary oral cancer team members, and standard clinical guidelines and protocols need to be conducted and followed to improve patient treatment outcomes. CLINICAL SIGNIFICANCE: Radiation stents have a significant role in reducing the complications of radiation therapy. Improving the knowledge and practice of radiation stents will have a substantial influence on the quality of health services provided for the oral cancer patients and their quality of life.

Oral rehabilitation of maxillofacial trauma using fixed corticobasal implant-supported prostheses: A case series.

INTRODUCTION: Maxillofacial trauma is associated with severe loss of soft and hard tissues that lead to aesthetic and functional disfigurements, adverse psychological impacts on the patient's general and oral health, and decreased quality of life. Therefore, treatment of maxillofacial trauma is challenging. PRESENTATION OF CASE: We present three patients with maxillofacial trauma owing to road traffic accidents that were rehabilitated by immediate use of loaded fixed corticobasal implant-supported prostheses with follow-up periods of 6, 5, and 7 years. All treated patients had a 100 % implant survival rate, healthy peri-implant tissues, stable prosthesis with significant improvement in mastication and phonation, and high patient satisfaction. DISCUSSION: Rehabilitation of patients with intensive maxillofacial trauma requires a multidisciplinary approach to ensure the standard of care during treatment. The described treatment eliminates the need for bone grafting, reduces susceptibility to grafting complications, shortens treatment time, and provides the patient with a fixed prosthesis with predictable success, excellent implant survival, healthy peri-implant tissue, improved prosthetic stability, and high satisfaction rates. CONCLUSION: Corticobasal implant-supported prostheses are a feasible treatment modality to rehabilitate patients with maxillofacial trauma with high success and survival rates and patient satisfaction.

Orthognathic correction and corticobasal implant-supported prostheses as a treatment modality for partial edentulism with mandibular prognathism: A case report and review of literature.

INTRODUCTION: Mandibular prognathism manifests as elongation of the mandible in the anteroposterior direction, resulting in a sunken appearance of the middle third of the face and sad look of the eyes. It adversely affects esthetics, function, and oral health, reducing the patients' self-esteem. It therefore presents a significant challenge. PRESENTATION OF CASE: A 23-year-old woman presented with prognathic features characterized by mandibular protrusion, maxillary retrusion, a prominent chin, and reduce self-esteem. Intraoral examination revealed multiple extracted teeth, severe fracture of the crown at 23, mobility of the fixed prosthesis on 13, 14, 15, and 16, a root stump of 18, and periodontally compromised teeth (31, 32, 33, 41, and 42). A multidisciplinary team formulated the following treatment plan: stage 1, orthognathic osteotomy to retrude the mandible at 34 and 44; stage II, fabrication of transitional acrylic partial dentures; and stage III: fabrication of definitive corticobasal implant-supported prostheses. The patient was delighted with the treatment and complied with the oral hygiene instructions and follow-up program. After 7 years of function, the patient presented without complaints and exhibited significant improvement in oral health, self-esteem, and quality of life. DISCUSSION: The management of mandibular prognathism requires a multidisciplinary approach. The treatment implemented was considered the optimal option that aligned with the recommendations of several researchers to reduce facial disfigurement and rehabilitate the edentulous state. CONCLUSION: The use of corticobasal implant-supported prostheses for the rehabilitation of patients with partial edentulism can significantly improve the treatment outcome following orthognathic surgery in cases with mandibular prognathism.

Rehabilitation of Patients with Compromised Ridge Support Using Immediately Loaded Corticobasal Implant-supported Prostheses: A Prospective Observational Study.

AIM: The aim of this prospective study is to evaluate the treatment outcomes and patient satisfaction following the use of fixed immediately loaded corticobasal implant-supported prostheses. MATERIALS AND METHODS: One hundred and seventy-four corticobasal implants (basal cortical screw, BCS implant design) were inserted in 20 consecutive patients with compromised ridge support. Implant survival and success were assessed using the James-Misch implant health quality scale and the Albrektsson criteria for implant success. The peri-implant health was evaluated at 1 week and 3, 6, 9, 12, and 18 months postoperatively. Moreover, the radiographic and prosthetic parameters and patient satisfaction were assessed. RESULTS: The implants showed optimum implant health and a 100% survival rate with none (0%) of the implants failing, mobile, lost, or fractured. Using Wilcoxon signed-rank test, significant decreases in both the modified gingival indexes and the probable pocket depth (PPD) and slight significant increases in the plaque index (PI) at 3, 9, 12, and 18 months and a nonsignificant increase at 6-month follow-up were reported with a range of 0-1. The calculus index (CI) was zero at all follow-up visits. Radiographic evaluations revealed increases in the bone-to-implant contact. Evaluation of the prostheses showed some treatable complications, and all the patients were satisfied. CONCLUSION: The use of corticobasal implant-supported prosthesis meets the patient's demand for an immediate, fixed treatment modality, with high survival and success rates, optimum peri-implant soft tissue health, and high reported satisfaction. CLINICAL SIGNIFICANCE: Corticobasal implants can improve the patient's esthetic, phonetic, mastication, and quality of life with the advantage of eliminating the need of bone grafting procedures.

Comprehensive prosthodontic treatment of an elderly patient with compromised ridges: a clinical case report / Tratamiento prostodóntico integral de un paciente anciano con proceso alveolar comprometido: informe de un caso clínico

Introduction: The objective of a complete denture prosthesis is restoring aesthetics, comfort, and function by the replacement of missing dental and alveolar structures employing a stable prosthesis. Case Report: Many conditions can complicate the treatment plan and fabrication of a complete denture prosthesis. Complete denture fabrication in clinically compromised conditions is a challenging task for the dentist. In this clinical report, we present comprehensive management of a patient with denture-induced hyperplasia, flabby ridge, and severely resorbed edentulous ridge. The three part strategy for management of the above-mentioned challenges can provide high-quality complete dentures, based on recognized prosthodontic principles. This first part will discuss the management of denture induced hyperplasia by elimination of the inflammation and excision of the lesion. Part two will cover management of the flabby ridge using a modified window technique for the impression of maxillary flabby tissues for an improved and controlled application of the impression material that is usually obtainable in dental practice. Part three highlights the rehabilitation procedure of the resorbed mandibular ridge using a functional impression technique with minimum soft tissue displacement and neutral zone arrangement of teeth to improve stability of the denture. Conclusion: rehabilitation of a patient with denture induced hyperplasia, flabby ridge, and severely resorbed edentulous ridges was successful.

Conclusion: La rehabilitación de un paciente con hiperplasia inducida por dentaduras postizas, cresta flácida y reabsorbida fue exitosa.

Detachable Lip and Cheek Plumper for Rehabilitation of Facial Disfigurement.

BACKGROUND: Hemimaxillectomy of acquired palatal defects may predispose the patient to hypernasal speech, leakage of fluids into the nasal cavity, impaired masticatory function, and swallowing difficulties leading to a detrimental impact on the quality of life. Sequentially, it can also affect individual character and trust in social life, leading to social phobia and anxiety. This article presents prosthodontic management of a young male patient with deformation of the entire right half of the face due to surgical removal of odontogenic myxoma. It describes a method where the clinician utilized a simple, noninvasive, and cost-effective technique to cut the weight of the obturator and to attain aesthetics, utilizing a detachable lip and cheek plumper. Case Presentation. A 19-year-old male attended the Prosthodontic Clinics at Faculty of Dentistry, the University of Khartoum, eight months after the surgical removal of a tumor. The chief complaint was difficulty eating or drinking. Furthermore, he dropped out of school because of his facial deformity and his indistinct voice. Medical and dental history revealed surgical resection of the entire right half of the maxillary alveolar bone due to myxoma. Intraoral examination revealed a well-healed surgical defect in the maxillary right buccal vestibule creating an oroantral communication. A treatment plan was formulated, keeping the patient's demand in mind. The decision was made to treat the patient with a maxillary obturator that would gain its support from the remaining teeth and tissues with a detachable cheek and lip plumper. The use of dental magnets as a means of attachment was elected. CONCLUSION: This article has described a simple, noninvasive, and cost-effective method to improve facial appearance in patients with hollow faces. The plumper prosthesis successfully improved the patient's appearance to the extent that comfort and function would permit and encourage self-esteem.

Enucleation and surgical stent as a treatment strategy for a large unicystic ameloblastoma: Case report and review of literature.

INTRODUCTION: Ameloblastoma is a benign neoplasm of odontogenic origin with local invasive characteristics and a high recurrence rate. It compromised 1% of the jaw's cysts and tumors with only 10-15% in children. PRESENTATION OF CASE: A 14-year-old boy sought treatment for a painless swelling involving the right side of the face started one year ago. The intra-oral examination displayed a firm mass associated with 46, 47 teeth, and the angle of the mandible. The radiographic examination revealed a large well-defined homogeneous radiolucency extending from the 46 region to involve the angle and extending towards the coronoid and condylar processes. An incisional biopsy confirmed the diagnosis of unicystic ameloblastoma. Treatment was planned according to the patient's age: Phase I: Surgical enucleation. Phase II: Construction and insertion of a surgical stent. Phase III: Construction of a transitional acrylic Kennedy class II partial denture. Phase IV: the patient is scheduled for a definitive implant-supported prosthesis at 18 years old. DISCUSSION: The management of ameloblastoma is influenced by the age of the patient, the extension, duration, and position of the lesion, and the histopathological variants. Several authors recommended enucleation as a conservative treatment approach to eliminate the esthetical, functional, and psychological squeals associated with the radical approach. The use of a surgical stent protects the enucleated cavity and promote tissue healing. CONCLUSION: Enucleation and subsequent surgical stent not only eliminates the disease, but also preserves the bone structure, prevents the facial disfigurement, and significantly improve the patient's esthetic, mastication, oral health, and quality of life.

Effects of Corticobasal Implant Protrusion inside the Nasal and Maxillary Sinus.

BACKGROUND: Implant protrusion into the nasal and maxillary sinuses presents a challenge in cases of severely resorbed maxillae. AIM: The aim of this study was to evaluate the clinical and radiographic effects of BECES® implant penetration depth into the nasal and maxillary sinuses. SETTING AND DESIGN: This was an observational study conducted in a tertiary institution. MATERIALS AND METHODS: Forty-nine BECES® implants were inserted into the maxilla of patients who presented with severely resorbed ridges but no history of sinusitis. Forty-five implants protruded into the sinus cavities. Patients were examined clinically and radiographically at 1 week and 3, 6, 12, and 18 months after insertion. Maxillary sinus health, survival and success rates, and peri-implant health were assessed using the plaque index (PI), calculus index, modified gingival index (MGI), and probing pocket depth (PPD). STATISTICAL ANALYSIS: Wilcoxon signed-rank test and Mann-Whitney test were used in this study. RESULTS: Four (8.16%) of the 45 implants that penetrated the cavities reached the sinus floor without disrupting the membrane; the penetration depth was ≥4 mm in 20 implants (44.44%) and <4 mm in 25 (55.56%). No patient showed clinical or radiographic signs of sinusitis during the observation period. There were significant differences in the PI, MGI, and PPD values between baseline and the 18-month follow-up with no association with the penetration depth. All implants showed radiographically direct bone-to-implant contact. Where the implant tip barely reached the sinus floor, the membrane healed uneventfully while when deeply penetrating the sinus, the membrane healed around the implant but did not cover the tip. All prostheses and implants survived during the observation period. CONCLUSION: Penetration depth of polished implants with cortical engagement into the maxillary sinus or the floor of the nose does not negatively affect implant survival, the success rate of the treatment, nor peri-implant soft-tissue health. It also does not provoke the development of sinusitis.

Rehabilitation of an irradiated marginal mandibulectomy patient using immediately loaded basal implant-supported fixed prostheses and hyperbaric oxygen therapy: A 2-year follow-up.

INTRODUCTION: The prosthetic rehabilitation of mandibular defects owing to tumor resection is challenging, especially when the patient has undergone subsequent radiotherapy. PRESENTATION OF CASE: A 46-year old male presented with a marginal mandibular resection. Following surgery, the patient received adjunctive radiation therapy with a total dose of 70 grays. On clinical examination, the patient presented with severely resorbed edentulous jaws, with an anterior marginal mandibular resection and an obliterated vestibular sulcus. The panoramic radiograph showed a hypocellularity of the maxillary and mandibular bones. A multidisciplinary team was formed, and a treatment plan was formulated which involved the construction of a vestibuloplast stent, and the application of 20 hyperbaric oxygen sessions before implant treatment and 10 more sessions after implant insertion. A total of 16 basal cortical screw implants were inserted to support the fixed prostheses, and a vestibuloplasty was performed to improve esthetics. No complications were observed, and at the 2-year follow-up, the patient presented with excellent peri-implant soft tissue health; increased bone-implant contact; and stable, well-functioning prostheses. DISCUSSION: The construction of a stable, retentive, well-supported removable prosthesis may be complicated in cases of comprehensive mandibular resection. Basal implants can eliminate the need for bone grafting, and reduce the treatment period required for providing a fixed prosthesis. CONCLUSION: To our knowledge this is the first evidence reporting the use of fixed basal implant-supported prostheses in irradiated bone, in conjunction with hyperbaric oxygen therapy. A treatment modality that significantly improves the peri-implant tissue health, and ensures an excellent implant-bone contact.

The Influence of Immediately Loaded Basal Implant Treatment on Patient Satisfaction.

BACKGROUND: Improving patient satisfaction and quality of life is of great importance when considering the different prosthetic treatment options for patients with severely resorbed residual alveolar ridges. We aimed to evaluate and compare patients' satisfaction when changing from fixed, removable, and/or conventional implant prostheses to basal implant-supported prostheses. METHODS: Sixty patients with a history of fixed, removable, and/or conventional implant prostheses who received basal implant-supported prostheses (BCS®, IHDE Implant System) were included in this study. Direct interviews were conducted using a four-section questionnaire that covered sociodemographic data, clinical examination, information on previous prostheses, and new implant information. The obtained data were statistically analysed using a Wilcoxon signed-rank test and chi-squared test. RESULTS: Patients were predominantly female, partially edentulous, and aged between 40 and 59 years. Patients' general satisfaction with basal implants was very high (7.7 out of 8). Patients' satisfaction with comfort, mastication, speech, and aesthetics significantly improved with the new basal implants. Males aged between 40 and 59 years and patients who had previously used both fixed and removable prostheses were generally the most satisfied. Although some patients had complaints, they still had high satisfaction and would choose the same treatment modality again. CONCLUSIONS: Basal implant-supported prostheses have a positive impact on oral health and highly increase patients' satisfaction.

Prosthetic rehabilitation of maxillary and mandibular gunshot defects with fixed basal implant-supported prostheses: A 5-year follow-up case report.

INTRODUCTION: Gunshot injuries to the oral maxillofacial region have serious aesthetic and functional consequences. PRESENTATION OF CASE: A 32-year-old male patient presented with a marginal mandibular resection owing to a gunshot wound. A clinical examination revealed destroyed crowns in teeth 12, 11, and 21; extraction in teeth 13, 22, 24, 31, 32-45; a fracture in tooth 38; and severe pain. Further, he had multiple submental scars and a completely obliterated sulcus. Consequently, a multidisciplinary team was formed who devised the following treatment plan: stage 1, root canal treatment for the maxillary anterior teeth, followed by crown construction and transitional mandibular removable partial denture construction, and stage 2, placement of immediately loaded basal implant definitive prostheses supported by 6 corticobasal screw implants. After 5 years of use, the patient presented with excellent peri-implant soft tissue health, prosthesis stability, and great improvements in aesthetics and function. The patient was highly satisfied with the treatment and restoration of his quality of life. DISCUSSION: Accurate treatment planning is vital for managing complicated cases, including gunshot defect cases, and should involve the selection of the most suitable reconstructive technique with lower susceptible complication rates and high success rates. The described treatment eliminates the need for bone grafting, reduces treatment duration, and involves fixed prosthesis placement. CONCLUSION: To our knowledge, this is the first report on basal implant-based full-mouth rehabilitation in a gunshot mandibular defect patient. The fixed hybrid basal implant-supported prosthesis produced highly acceptable aesthetic and phonetic results and greatly improved the patient's life.

A Novel Approach for Rehabilitation of a Subtotal Maxillectomy Patient with Immediately Loaded Basal Implant-Supported Prosthesis: 4 Years Follow-Up.

The prosthetic rehabilitation of maxillary defect can be achieved successfully by using an implant-supported prosthesis. The use of remote bony areas such as the zygomatic bone in cases of large defects provides an innovative substitute for free vascularized osteocutaneous flaps and the solution to flap failures. This report describes the rehabilitation of a 22-year-old female with a subtotal maxillectomy using an immediately loaded basal implant-supported prosthesis. Four basal cortical screw implants (BCS®) are inserted; 1 on the contralateral nasal floor, 2 implants in the pterygoid plates, and the last in the zygomatic bone using cone beam computed tomography scans. The prosthesis was constructed and cemented in 3 days. The surgical and prosthetic procedures were performed without any obstacles. After 4 years in function, the patient was highly satisfied with the treatment as it improved her mastication, speech, aesthetic and returned her self-esteem. To our knowledge, this is the first clinical report detailing the use of basal implant-retained obturator in a subtotal maxillectomy patient.

Full-mouth rehabilitation of a patient with cleidocranial dysplasia using immediately loaded basal implant-supported fixed prostheses: A case report.

INTRODUCTION: Cleidocranial dysplasia (CCD) is a rare congenital disease characterised by generalised skeletal and orofacial defects. The dental rehabilitation of patients with CCD is a case-sensitive procedure requiring a multidisciplinary approach. PRESENTATION OF CASE: A 24-year-old woman presented with the skeletal and oral manifestations of CCD, including multiple poorly erupted and impacted teeth. The patient was very depressed and rejected orthodontic treatment; therefore, we formulated a treatment plan involving extraction of all impacted and poorly erupted teeth under general anaesthesia, followed by fabrication and delivery of transitional complete dentures for cosmetic, functional, and psychological benefits. Three months later, 14 screw basal implants were inserted in the maxillary and mandibular jaws and subjected to immediate loading with fixed prostheses 3 days later. At the 3-year follow-up visit, the patient expressed satisfaction with the aesthetic and functional aspects of the prostheses and presented with excellent oral health. DISCUSSION: The timing of diagnosis, patient's age, willingness to undergo the planned treatment, and treatment duration are valuable considerations for establishing an appropriate treatment plan for the oral manifestations of CCD. CONCLUSION: To our knowledge, this is the first report on basal implant-based full-mouth rehabilitation in a patient with CCD. Basal implant-supported prostheses may be useful for patients with CCD who present with a limited bony foundation after tooth removal. The treatment requires lesser time than orthodontic treatment, eliminates the need for bone grafting, spares the patient from ill-fitting dentures, reduces the overall cost, and improves the quality of life.
