Troubleshooting Vaginal Stents: A Critical Review of Common Problems and Solutions.

This review aims to examine the use of vaginal stents in clinical practice, specifically for treating vaginal agenesis and related complications and problem associated with vaginal stents. Vaginal agenesis, also known as Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome, is a congenital disorder characterized by the uterus not developing or developing only partially. Vaginal stents are medical devices that preserve the structural integrity and patency of the vaginal canal after trauma or surgery. They play an important part in gynecological treatments such as post-radiation therapy, reconstructive surgery, and vaginal stenosis management. The review also discusses the primary applications of vaginal stents, such as preventing adhesions, healing mucosa, and maintaining patency. It also investigates frequent concerns associated with stent use, such as complications and the need for better designs. Vaginal stents are essential in a variety of therapeutic settings, providing major benefits in maintaining vaginal tissue and function. However, their use is fraught with complications, including the risk of infection, discomfort, and the possibility of inappropriate placement.

An Alternative Approach for the Rehabilitation of a Complete Denture Patient With Parkinson's Disease.

Parkinson's disease (PD) affects one to two out of every 1,000 individuals. PD, being age-related, is affecting a percentage of those over and around the sixth decade. Lewy bodies containing α-synuclein and a reduction in dopaminergic neurons in the substantia nigra, which impairs the region's capacity to promote voluntary movements, are the main neuropathological findings. The three main symptoms of PD are stiffness, bradykinesia, and tremor. Treatment of edentulous conditions in patients with PD becomes a challenge due to decreased neuromuscular coordination and decreased mobility. This case report outlines a 64-year-old male patient with complete edentulism suffering from PD. Complete denture fabrication was done using the concepts of the neutral zone and denture characterization. Significantly, it not only improves the stability of the dentures but also establishes good denture aesthetics.

Clinical Dilemma: Flabby Ridges and the Quest for Aesthetic Denture Fit.

A flabby ridge is a hyperplastic and movable soft tissue that affects both maxillary and mandibular ridges most commonly the maxillary anterior region. This tissue that supports the denture is dynamic and can be dislodged by masticatory pressures, which affects denture stability and causes a loss of peripheral seal. The mobile tissue may be distorted as a result of forces applied during the impression-making process. For dental practitioners, fabricating dentures on a flabby ridge might be a Herculean endeavor because the dentures may not be stable and may not yield satisfactory outcomes. When treating such patients, practitioners should use extra caution. While treating such circumstances, adjustments to standard impression processes can be helpful. There are several ways to address flabby ridges, such as implant therapy, balanced occlusal load distribution, surgical management, and unique impression techniques. In this case report, a patient with a flabby ridge is treated prosthodontically via an alternative impression approach.

The Reconstruction of Post-traumatic Cranial Bone Depression by Duplicating an Autogenous Bone Flap With a Prosthetic Polymethyl Methacrylate Cranial Stent.

Cranioplasty is a common surgical procedure used to restore the shape of the calvaria. Autogenous bone flaps provide biological repair with the least morbidity to the donor location. One method for reusing bone autograft during cranioplasty involves low-temperature preservation followed by autoclaving. According to the literature, there was a good to modest improvement in the skull's symmetry, cosmesis, scars, and contour. It was determined that autoclaved frozen autogenous cerebral bone flaps are a safe and reliable method of cranioplasty. Despite its apparent simplicity, cranioplasty has been found to carry a relatively high complication rate, ranging from 12% to 50%, which starkly contrasts with the standard elective craniotomy, with a complication rate typically ranging from 24% to 60%. Complications associated with autogenous bone flap procedures are varied. The presented case report primarily focuses on the duplication of autogenous bone flaps by using clear polymethyl methacrylate.

Effect of Photobiomodulation on Crestal Bone Density Around Dental Implants: A Case Report.

Dental implants are becoming a necessary component of the dental profession. The first bone resorption at the implant surface has an impact on implant success. Bone alterations surrounding the implant are a significant factor in determining the implant's effectiveness. Reducing the loss of peri-implant crestal bone has been a constant goal. In dental implantology, several procedures are carried out to improve implant stability and the healing of the bone. The ability of photobiomodulation techniques or low-level laser therapy (LLLT) to speed up osseointegration by inducing cellular metabolism and stimulating tissue healing has made them popular. This case study details the implant loading in a patient treated with photobiomodulation to achieve implant stability and who has compromised bone type or D4.

Aesthetic and Functional Rehabilitation for Dentogingival Asymmetry Using Zirconia Restorations.

In an effort to improve dentogingival aesthetics, scientific research has been developing non-surgical techniques and dental restorative materials. A 45-year-old female reported to the hospital with a complaint of an unpleasant aesthetic in the anterior region of the maxilla. She has an irregular contour of the gingiva in her anterior region and no temporomandibular problems. There is a history of trauma, but she did not take any treatment for it, which caused discolouration. Plaque index was retained by the surface roughness. Due to this reason, the patient's appearance, self-esteem, and quality of life have decreased. The purpose of this case is to provide a system-based clinical example of oral rehabilitation for anterior teeth. The patient didn't like the way she looked, and hence aesthetic and functional rehabilitation was planned. Treating the dentogingival asymmetry was the first step in the therapeutic approach. An in-ceram zirconia permanent porcelain metal-free crown was positioned after the temporary crowns were cemented into place. It should be mentioned that in clinical situations, the integration of periodontal and prosthetic treatment is crucial. Additionally, it is stated that the in-ceram zirconia system can produce satisfactory results when applied appropriately. For the main anterior teeth, zirconia crowns have offered an alternate treatment option that addresses aesthetic concerns and facilitates the installation of extra-coronal restorations. This article describes a case involving the aesthetic and functional restoration of severely damaged maxillary incisors using zirconia crowns.

Addressing Flabby Ridges in Complete Denture Patients: A Case Report.

A common clinical condition affecting the alveolar ridges of the mandibular or maxillary arches is known as a "flabby ridge." This condition involves a superficial region of movable soft tissue. It is particularly prevalent among long-term denture users, especially in the lower anterior region. Flabby ridges occur when hyperplastic soft tissue replaces the alveolar bone, resulting in mobile, hypermobile, and frequently edematous tissue. This condition is most commonly found in the edentulous areas of the oral cavity, especially in the maxillary anterior region. To provide a good fit for the patient, it is necessary to create a denture with accurate morphology, unique contours, and mobility of flabby tissue. The presence of a flabby ridge can significantly impact the stability, fit, and functionality of dentures. Management of flabby tissue includes various methods such as impression techniques, surgical intervention, and denture designing. This case report aims to provide an improved and controlled application of polyvinyl siloxane impression material in managing flabby tissue conditions, which is commonly used in dental practices. It presents a modified window technique for making impressions of anterior mandibular flabby tissues with their natural, undistorted state, leading to a more accurate and stable denture fit.

Enhancing Facial Aesthetics Using a Novel Technique: A Case Report.

A person's facial appearance matters in both social and professional contexts. Losing teeth has an impact on phonetics and mastication, but it also has an aesthetic effect on the lower face's appearance. Cheek sinking is caused by a decrease in muscular tone and an increase in the rate of resorption of the alveolar ridges. An edentulous patient will transform aesthetically if they receive facial as well as dental rehabilitation. The patient's social contacts and sense of self-worth both improve as a result. When an individual exhibits significant alveolar process resorption, traditional dentures are unable to offer sufficient support, hence requiring supplementary cheek support. Appliances for elevating or plumping the cheeks can be used for this. A 68-year-old male patient reported to the department of prosthodontics with a chief complaint of missing teeth and poor aesthetics. After a complete examination, a complete denture prosthesis with a detachable cheek plumper was planned. Press button retention for cheek plumpers is an advantage due to its easy installation and use. This article outlines a straightforward, inexpensive, and non-invasive process for creating a non-detachable cheek plumper using a press button for those who are edentulous. The two-in-one prosthesis enhances the appearance of the face while also replacing lost teeth.

Influence of Crown Height and Width on Marginal Bone Loss and Long-Term Stability of Dental Implants: A Systematic Review.

Still, a major focus of research in implantology is how crown height and width affect marginal bone loss (MBL) and the long-term durability of dental implants. Maximizing the success of implants and lowering problems depends on an awareness of these elements. Following the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines, this systematic review searched pertinent studies across several databases using keywords unique to databases. Studies on MBL and long-term implant stability evaluated in the review included those on crown height and width, horizontal and vertical cantilevers, and prosthesis dimensions. In the chosen studies, we found that both implant success and crestal bone loss were greatly influenced by crown height and width. Particularly in the posterior sections, horizontal cantilevers were connected to both increasing MBL and mechanical problems. Vertical cantilevers also affected MBL; however, their impacts were more obvious in circumstances with greater crown heights. Greater prosthesis widths, especially in the mandibular molar area, were linked to higher MBL. Bone density and insertion torque (IT) were the main determinants of MBL, more than the primary implant stability quotient. Early MBL was influenced by abutment height, mucosal thickness, and implant insertion depth; bone levels stabilized six months later. Short implants allow single crowns to be supported, but in some cases, a higher failure rate was seen. The success and stability of dental implants were found to be mostly dependent on crown height, width, and cantilever design. MBL and long-term stability are greatly influenced by horizontal and vertical cantilevers, which calls for careful design and planning. With specific care for bone density, IT, and early MBL stabilization, both short and standard implants can produce equivalent results. These results highlight the need for customized treatment plans to maximize implant success and lifetime.

Prevalence of Osteoporosis and Its Effect on Residual Ridge Resorption in Postmenopausal Females of Rural Central Indian Region.

MATERIALS AND METHODS:  A study was conducted with 60 postmenopausal female individuals. BMI was calculated using the weight and height of the patient using a formula. BMD was assessed and graded using a T-score. RRR was determined using the Tallgren method. RESULTS: Most individuals showed a higher BMI (63.33%), which is in the overweight or obese category. BMD was lower in approximately 68.33% of patients, and RRR was significantly higher in about 60% of total patients. CONCLUSION: The higher the BMI values, the lesser the BMD and the higher the RRR.

Prosthodontic Rehabilitation of the Flabby Edentulous Maxilla Using Hobkirk's Technique: A Case Report.

Edentulism is characterized by the loss of teeth, which can significantly impact oral health and the quality of life of older patients. Among the challenges faced by individuals with edentulism is the occurrence of flabby ridges, a common consequence of prolonged tooth loss. Flabby ridges, characterized by soft, compressible tissue in the edentulous ridge area, present unique management challenges for dental professionals. Fibrous or flabby alveolar ridges present challenges in the fabrication of predictable prostheses. Impression making, a critical step in prosthodontic treatment, becomes particularly problematic as forces exerted during the process can distort the mobile denture-bearing tissues, which will cause the denture to become unstable and loose. This case report aims at an impression technique that can enhance the treatment outcomes for edentulous patients with fibrous alveolar ridges as this decreases the pressure over flabby tissue.

Refining Complete Dentures: Optimizing Results with Enhanced Phonetics and Esthetics.

Tooth loss and subsequent complete denture rehabilitation can profoundly affect a patient's psychological and social well-being. Dentures play an important role in helping individuals regain a sense of normalcy as well as facilitating communication in today's appearance-conscious society. However, common issues with dentures include discomfort while chewing and dissatisfaction with esthetics and speech. Prosthetic rehabilitation for complete denture patients should aim not just at replacing missing teeth but at fully restoring masticatory functions and appearance. This article outlines a simple, economical, and esthetically pleasing approach to rehabilitating patients with complete dentures, particularly those with resorbed ridges and with difficulty in phonetics. The focus is on comprehensively restoring the patient's orofacial complex.

Dual-Arch Prosthesis: Revolutionizing Partial Dentate Rehabilitation.

The utilization of natural teeth as denture abutments offers a significant advantage in retarding the residual ridge resorption (RRR). This approach distributes stress concentration between the denture-bearing areas and abutment teeth, thereby mitigating issues such as loss of sensory feedback, compromised mastication, and aesthetic concerns. Overdentures, by providing additional support and stability, play a pivotal role in reducing RRR while enhancing stability and retention. A cast partial denture (CPD) becomes the first choice in cases of long edentulous span where cross-arch stabilization is required. The simplicity of insertion, removal, and maintenance, coupled with effective oral hygiene practices, make CPDs a practical solution. This case presentation illustrates the successful prosthetic rehabilitation of a partially dentate patient through the implementation of a maxillary overdenture and mandibular CPD underscoring the efficacy of this treatment modality in achieving optimal outcomes. The combination of these prostheses restored the masticatory function, improved the aesthetics, and enhanced the quality of life of the patient. This case highlights the effectiveness of dual-arch prosthetic solutions in achieving comprehensive rehabilitation in partially dentate patients.

Rehabilitation of the Surgical Defect Secondary to Mucormycosis With a Definitive Obturator: A Case Report.

Neglect initially starts as an infection, evolving into a disease. During the COVID-19 pandemic, lifestyle changes and disturbed food intake have weakened immune systems, making individuals more susceptible to secondary infections. Mucormycosis poses a significant threat, especially during the COVID-19 pandemic when immune systems may be compromised. The impact of the disease extends beyond physical health, affecting psychological and social well-being due to the challenges, such as difficulties in mastication, speech, and swallowing post-surgery. The mention of maxillectomy highlights the severe nature of some cases, necessitating surgical intervention to remove the affected tissue. Anatomical and functional losses following surgical excision of the maxilla and surrounding tissues need to be recovered as soon as possible. After surgery, prostheses can and should be used to restore speech, mastication, and deglutition - three essential physiological activities. Thus, a patient's treatment approach should include prosthetic planning before surgical intervention and rehabilitation after the surgery. If they are carefully handled at the moment of surgery, the overall continuity created by maxilla resection includes at least the oral, nasal, and maxillary sinus cavities, which may prove to be a useful future location for prosthesis retention. As a result, the prosthodontist's role becomes crucial in assisting the surgeon in taking all necessary precautions that are beneficial to the patient.

Osseodensification: An Innovative Technique With Manifold Gains.

Prosthodontics, which is removable and fixed, is the branch dealing with the replacement of missing teeth. Implant therapy is the popular treatment modality and commonly preferred treatment option by many patients and clinicians for missing teeth in recent years. Primary implant stability (PIS) is one of the crucial factors for osseointegration. It has been considered a crucial factor in the success of implants. Moreover, several factors influence PIS. On the other hand, both secondary implant stability and osseointegration are influenced by the PIS. Bone density, bone volume, bone-to-implant contact, and other factors that enhance or degrade the primary stability. Certain host sites such as the maxillary posterior region demand more dense bone to achieve desired results as they are the low-density areas of the jaw. So, a new promising and growing innovative concept of osseodensification (OD) offers a great solution with multiple benefits and desirable results. This review article aims to enlighten the multiple benefits of OD technique and their mechanism of action.

Fabrication of Hollow Acrylic Vaginal Stents Using Frozen Coconut Oil for Vaginal Agenesis Management.

In a rare condition known as vaginal agenesis, the uterus (womb) may develop only partially or not at all, while the vagina fails to develop altogether. It is common to diagnose vaginal agenesis, when a female does not start menstruation at puberty. This is a prenatal disorder that may also be linked to bone or kidney issues. Mullerian agenesis, Mullerian aplasia, and Mayer-Rokitansky-Kuster-Hauser (MRKH) syndrome are other names for the illness. Treatment modalities encompass surgical and nonsurgical interventions, including the utilization of prefabricated or customized vaginal stents for neovagina reconstruction and maintenance. This case report describes the development of a neovagina in a 27-year-old female diagnosed with vaginal agenesis, a characteristic of MRKH syndrome. A customized clear acrylic stent, designed to provide a resilient surface, serves as a straightforward and cost-efficient alternative for managing this condition. Significantly, it enhances patient's compliance and comfort during treatment, addressing both the physical and psychological ramifications of this congenital anomaly. This customized vaginal stent not only provides a practical solution but also contributes to enhancing the quality of life for individuals grappling with vaginal agenesis, thereby offering a promising avenue for addressing the multifaceted challenges associated with this condition.

Optimizing Implant Placement in Cases of Limited Interocclusal Space: Strategies and Challenges.

Effective treatment planning is crucial for implant-supported dental prostheses' success, requiring a thorough assessment of various factors, including bone quality, quantity, and available space. Evaluating space availability, encompassing height, width, and angulation, is imperative to ensure optimal implant positioning devoid of anatomical limitations. Adequate vertical space is essential for accommodating the implant-supported restoration while preserving proper occlusal function and esthetics. However, not all cases adhere to ideal standards, especially those featuring limited interocclusal space, as seen in scenarios of long-standing edentulous areas lacking prior prosthetic rehabilitation. Ideally, the interocclusal space should measure between 8-12 mm vertically. This case report details the management of reduced interocclusal space through the strategic placement of deeply positioned implants and the incorporation of a screw-retained fixed partial denture, effectively addressing the challenges associated with limited space.
