RESUMO

Due to the highly predictable long-term clinical outcomes, modern implant dentistry has become one of the most preferred treatment modalities for restoring missing teeth. However, the complications of implant therapy compromise the long-term implant success and remain a great challenge to clinicians. Hardware complications include the mechanical complications which are related to the manufacturer-fabricated components of the prosthesis, such as abutment/screw loosening, fracture and implant fracture; and the technical complication which are related to laboratory-fabricated components of the prosthesis, such as veneer chipping. The biological complications mainly include peri-implant mucositis and peri-implantitis. It is crucial to figure out how to effectively avoid and manage the complications of implant therapy. This article reported the definitions, incidences, risk factors, prevention and treatment of both mechanical and biological complications of implant therapy.

RESUMO

In this review, we have discussed the relationships between oral squamous cell carcinoma (OSCC) and dental implants. In the last decade, dental implants have been widely used for the treatment of complete or partial edentulism. Despite the fact that they have seen incredible success and the use of dental implants increases, concerns over safety and efficiency is rising as well. The literature analysis has shown that the number of reported cases when the OSCC development is associated with peri implantitis is gradually increasing. The possibility of squamous cell carcinoma development must be considered when evaluating the peri-implantitis. We highly recommend periodic oral and radiographic examination after the implant placement. The patients with peri-implantitis that do not respond to conventional treatment methods, and the patients who have a severe or rapid progression of peri-implantitis require biopsy. The histopathological examination will aid with the differential diagnosis between peri-implantitis and OSCC, and hence, provide the correct diagnosis.

RESUMO

This investigation was designed to evaluate the reestablishment of bone-to-implant contact on infected dental implant surfaces following decontamination with an erbium, chromium:yttrium-scandium-gallium-garnet (Er,Cr:YSGG) laser and reconstructive therapy. Three patients presenting with at least one failing implant each were enrolled and consented to treatment with the Er,Cr:YSGG laser surface decontamination and reconstruction with a bone replacement allograft and a collagen membrane. The laser treatment was carried out at a setting of 1.5 W, air/water of 40%/50%, and pulse rate of 30 Hz. At 6 months, all three patients returned for the study. En bloc biopsy samples of four implants were obtained and analyzed. Two patients had excellent clinical outcomes, while one patient with two adjacent failing implants experienced an early implant exposure during the follow-up period. There was histologic evidence of new bone formation with two implant specimens and less bone gain with the others. Despite the small sample size, these were optimistic findings that suggested a positive role of Er,Cr:YSGG laser in debridement of a titanium implant surface to facilitate subsequent regenerative treatment. This investigation provides histologic evidence as well as encouraging clinical results that use of the Er,Cr:YSGG laser can be beneficial for treatment of peri-implantitis, but further long-term clinical studies are needed to investigate the treatment outcome obtained.

RESUMO

A link between periodontitis and cardiovascular disease has been reported in the literature. For this systematic review, the keywords "cardiovascular disease" (CVD) were combined with "periodontitis" and "peri-implantitis" and were used to search for literature published on MEDLINE and PubMed between 1990 and 2020. Hand searching was also performed. A total of 206 articles were identified, 51 of which were reviewed. A link between periodontal disease and CVD can be explained by both the infection and inflammatory pathways. Interventional studies on the treatment of periodontal disease related to CVD have shown conflicting results. Therefore, based on published studies, CVD should presently be considered a comorbidity of periodontitis (with an association but no direct cause and effect documented). The association of CVD with peri-implantitis has too few studies to draw any conclusions. More studies are necessary before any conclusions can be made between CVD and periodontitis and CVD and peri-implantitis regarding possible links and the extent of association.

RESUMO

The significance of keratinized mucosa around dental implants for the prevention of biologic complications has been a subject of controversy. Agreement, however, exists on the benefits provided to achieve more satisfactory oral hygiene measures and reduced clinical inflammation. A prospective interventional case series of 14 patients (31 implants) were examined every 3 months for up to 12 months. The effect of soft tissue conditioning by means of free autologous epithelial graft on the management of peri-implantitis with supracrestal and/or dehiscence-type defect morphology was evaluated. All clinical parameters were significantly reduced (P < .001), with complete disease resolution in 78.6% of the patients and 87.1% of the peri-implantitis implants. Unsuccessful cases were associated with less gain of keratinized mucosa, deep probing pocket depths, bleeding on probing, and less satisfaction during brushing at 12 months. Dimensional changes following soft tissue grafting were more significant during the first 3 months and led to a 42.4% shrinkage at 12 months. Soft tissue conditioning by means of free autologous epithelial graft in combination with apically positioned flap is a viable and effective therapy to manage peri-implantitis associated with deficient keratinized mucosa.

RESUMO

Many, mostly older patients suffer from osteoporosis: a chronic skeletal disease causing bone to become more porous and less strong. 2 recent systematic reviews and one long-term prospective multicentre case-control study showed that placing implants in osteoporosis patients is not contraindicated. From these studies it can be concluded that results comparable to those with patients who do not suffer from osteoporosis can be reached. Osseointegration, implant survival rate, marginal bone loss and mucosal parameters do not behave differently than they do in the healthy group of patients.

RESUMO

The aim of this case report was to report the course of treatment for advanced paranasal sinus infection triggered by peri-implantitis, managed using functional endoscopic sinus surgery (FESS), with outcomes. A nonsmoking male patient received sinus augmentation with implant placement on his left posterior maxilla 15 years ago. Possibly due to noncompliance to maintenance, peri-implantitis developed and progressed into the augmented bone area in the maxilla. Eventually, maxillary sinusitis occurred concomitantly with a spread of the infection to the other paranasal sinuses. Implant removal and intraoral debridement of inflammatory tissue were performed, but there was no resolution. Subsequently, FESS was performed, with removal of nasal polyp and sequestrum. After FESS, the patient's sinusitis resolved. Histologically, the sequestrum was composed of bone substitute particles, necrotic bone, stromal fibrosis, and a very limited cellular component. Two implants were placed on the present site, and no adverse event occurred for up to 1 year after the insertion of the final prosthesis. Peri-implantitis in the posterior maxilla can trigger maxillary sinusitis with concomitant infection to the neighboring paranasal sinuses. FESS should be considered to treat this condition.

RESUMO

Osteonecrosis of the jaw is a possible oral complication resulting from antiresorptive therapies, such as bisphosphonates (Bfs). Although the etiology is not entirely clear, it has been shown to be dependent on several factors, with the traumatic stimulation caused by the placement of teeth implants indicated as one of the predisposing factors to this pathology. The indications and preventive methods for performing these procedures have been questioned, making it essential to determine the proper protocols. Thus, the present study aims to discuss the risks of the development of osteonecrosis in patients undergoing dental implant surgery who use Bfs as well as to discuss related local and systemic factors and possible methods for preventing this side effect. The study also aims to present a clinical case of an osteopenic patient who used Bfs and underwent rehabilitation through implants according to specific protocols, which resulted in successful treatment.

RESUMO

PURPOSE: This investigation aimed to evaluate clinical, prosthetic, and patient-based outcomes of a milled bar with polyether ether ketone (PEEK) and metal housings for inclined implants supporting mandibular overdentures. MATERIALS AND METHODS: Eighteen edentulous participants received four implants in the interforaminal area of the mandible (two vertically and two distally inclined), and implants were connected with milled bars. Overdentures were attached to the bars with PEEK female housing (test group). The control group consisted of participants who received milled bar overdentures with conventional metal housings but were case matched to the test group and served as a historical cohort. Clinical parameters (Plaque Index, Gingival Index, pocket depth, and bone loss) were measured at baseline, 6 months, and 12 months. Patient satisfaction (using visual analog scale) and prosthetic complications were recorded after 12 months. RESULTS: The control group showed a significantly higher plaque score and marginal bone resorption compared with the test group. The test group showed higher satisfaction with retention, stability, speech, and esthetics compared with the control group (P < .048). The test group showed a significantly lower incidence of female housing wear (P = .017), plastic clip wear (P < .001), and plastic clip fracture/renewal (P = .049) than the control group. No difference between groups was noted for other clinical, prosthetic, and patient-based outcomes. CONCLUSION: PEEK housing of a milled bar may be a successful alternative to conventional metal housing for inclined implants supporting mandibular overdentures, as it is associated with favorable clinical, prosthetic, and patient-based outcomes after 1 year.

RESUMO

PURPOSE: To describe the prevalence of alveolar bone atrophy in edentulous arches of elderly individuals in relation to insertion of dental implants and the eventual need for bone grafting procedures. MATERIALS AND METHODS: Computed tomography scan files of 228 edentulous arches of elderly patients (ages 65 to 100 years) were evaluated in relation to implant placement. Six measurements per arch were taken on cross-sectional reconstructions. Bone atrophy categories were described, in relation to implant placement, for the anterior and posterior sections of the arches. Six bone sections per arch were evaluated and allocated to the predetermined categories. Prevalence of each type of atrophy was calculated. RESULTS: In the maxilla, only 5.0% of the patients showed a bone anatomy capable of receiving implants without any augmentation both in the posterior and anterior regions; 64.4% showed the need for major reconstruction in both areas. In the mandible, 17.3% of the patients did not require any augmentation in both regions; 9.4% were in need of major reconstruction in both areas. The anterior part of the arches could eventually be treated without any bone augmentation in 10.9% of the maxillae and 72.4% of the mandibles, while minor augmentation was needed in 16.8% of maxillae and 15.8% of mandibles. CONCLUSION: Most edentulous elderly patients show some degree of alveolar bone atrophy. It is often feasible to insert implants in the anterior mandible to support a restoration. In most maxillary cases, alveolar atrophy calls for augmentation procedures in both the anterior and posterior areas. In elderly individuals, the anterior maxilla often shows bone deficiency interfering with simple implant placement procedures, thus also limiting the use of tilted implants.

RESUMO

ABSTRACT Introduction: The placement of dental implants is based on the creation of optimal conditions in the remnant bone. In some cases, it is indispensable to perform bone regeneration procedures and use barrier membranes to create such optimal conditions capable of favorably supporting the dental implant. Objective: Describe alternatives of barrier membranes in cases of guided bone regeneration. Case report: A female 53-year-old patient presents with a gingival fistula attached to tooth 14. Root fracture is diagnosed and extraction is conducted. Next, alveolar biomodification is performed to carry out guided bone regeneration and placement of a fibrin-rich plasma membrane. When healing is complete dental implants will be placed. Conclusions: The use of barrier membrane alternatives has shown to be effective in cases of guided bone regeneration(AU)

RESUMO

ABSTRACT Background: The occurrence of a vestibular bone lamina dehiscence of a fresh alveolus becomes a challenge for rehabilitation treatment of dental implants. Objective: To evaluate prosthetic treatment and stability of periimplant soft tissues in an alveolus with advanced oral bone resorption immediately after extraction, by using single fixed prostheses on a dental implant. Case presentation: A 29-year-old female patient, without systemic disease, completely toothed, with a thick-scalloped gingival biotype, attended the clinic and her main reason for consultation was not being aesthetically satisfied with her right upper central incisor. Radiographic examination showed advanced oral bone loss, secondary to an infection of the root of the right upper central incisor. In a first surgical phase, the right central incisor was extracted using a traumatic technique with periotomes, and a dental implant was placed. A resorbable membrane was adapted to the vestibular defect and the particulate cortical bone allograft was then compacted into the site in order to fill the space between the collagen membrane and the dental implant. A screw-retained provisional restoration was performed using the extracted natural tooth. The emergence profile was established simply by adding fluid composite resin, until the desired contours were achieved. Radiological and clinical follow-up at six months showed favorable implant evolution. No mechanical or biological complications were observed during this observation period. The oral gingival margin was in a correct position. Conclusion: This technique allowed predictable aesthetic-functional outcomes and soft tissue stability in a thick-scalloped gingival biotype with a single fixed prosthesis.


RESUMEN Antecedentes: La presencia de una dehiscencia de la lámina ósea vestibular de un alveolo fresco se convierte en un desafío en el tratamiento de la rehabilitación con implantes dentales. Objetivo: Evaluar el tratamiento protésico y la estabilidad de los tejidos blandos periimplantarios en un alveolo con reabsorción ósea bucal avanzada inmediatamente posterior a una extracción, mediante el uso de prótesis fijas unitaria sobre implante dental. Presentación del caso: Una paciente de 29 años de edad, sin enfermedad sistémica, completamente dentada, con un biotipo gingival festoneado grueso, asiste a la clínica y su principal motivo de consulta fue no estar conforme estéticamente en su incisivo central superior derecho. El examen radiográfico mostró la presencia de una pérdida ósea bucal avanzada, secundaria a una infección de la raíz del incisivo central superior derecho. En una primera fase quirúrgica, se extrajo el incisivo central derecho utilizando una técnica atraumática usando periótomos y se colocó un implante dental. Se adaptó una membrana reabsorbible al defecto vestibular y después se compactó el aloinjerto de hueso cortical particulado en el sitio para llenar el espacio entre la membrana de colágeno y el implante dental. Se realizó una restauración provisional atornillada utilizando el diente natural extraído. El perfil de emergencia se estableció simplemente agregando resina compuesta fluida, hasta que se lograron los contornos deseados. El seguimiento radiológico y clínico a los 6 meses mostró una evolución favorable del implante. No se observaron complicaciones mecánicas ni biológicas durante este periodo de observación. El margen gingival bucal estaba en una posición correcta. Conclusión: Esta técnica permitió resultados estéticos-funcionales predecibles y estabilidad de los tejidos blandos en un biotipo gingival festoneado grueso con una única prótesis fija.

RESUMO

OBJECTIVES: To assess peri-implant tissue conditions on the short term in patients receiving the Sub-periosteal Peri-implant Augmented Layer (SPAL) technique and in patients with adequate thickness (≥2 mm) of the peri-implant buccal bone plate (PBBP) at placement. METHODS: Patients where either a dehiscence defect or thin PBBP at implant placement was corrected by SPAL technique (SPALdehiscence and SPALthin groups, respectively) and patients presenting a residual PBBP thickness ≥2 mm at implant placement (control group) were retrospectively selected. The number of peri-implant sites positive to bleeding on probing (BoP) at 6 months following prosthetic loading was the primary outcome. Also, height of keratinized mucosa, marginal soft tissue level, Plaque Index, peri-implant probing depth, suppuration on probing, and interproximal radiographic bone level (RBL) were evaluated. RESULTS: Thirty-four patients (11 in the SPALdehiscence group, 11 in the SPALthin group, and 12 in the control group) were included. In each SPAL group, 10 patients (90.9%) showed peri-implant tissue thickness ≥2 mm at the most coronal portion of the implant at uncovering. The prevalence (number) of BoP-positive sites was 2, 1, and 0 in the SPALdehiscence , SPALthin , and control groups, respectively. RBL amounted to 0.3 mm in the SPALdehiscence group, 0.2 mm in the SPALthin group, and 0 mm in the control group. CONCLUSION: After 6 months of prosthetic loading, patients treated with SPAL technique show limited peri-implant mucosal inflammation in association with shallow PD and adequate KM. At implants receiving SPAL technique, however, interproximal RBL was found apical to its ideal position.

RESUMO

OBJECTIVES: The aim was to evaluate the overall occurrence and potential clustering of biological and technical complications in implant dentistry. MATERIAL AND METHODS: 596 patients provided with implant-supported reconstructions were evaluated for the occurrence of (a) technical complications, (b) peri-implantitis and (c) implant loss during a period of 9 years. Time and type of event were scored, and potential risk factors were explored through parametric modelling of survival and hazards. Clustering of complications was assessed at the patient level, and patient satisfaction was evaluated by questionnaire completed at the 9-year examination. RESULTS: 42% of patients were affected by technical and/or biological complications during the 9-year observation period. Extent of therapy (Hazard Ratio 2.5: patients with partial jaw restorations; HR 3.9: patients with full jaw restorations) and a history of periodontitis (HR 1.6) were identified as risk factors. While technical complications occurred mostly as isolated events, 41% of subjects identified with peri-implantitis and 52% of subjects with implant loss also presented with other complications. The hazard for technical complications and implant loss peaked at 0.7 years and 0.2 years, respectively, while the hazard for peri-implantitis was consistent throughout the observation period. The overall proportion of satisfied patients at 9 years was high (95%), and only minor differences between individuals with and without complications were noted. CONCLUSIONS: Complications following implant-supported restorative therapy were common findings. Extent of therapy and periodontitis were identified as risk factors. While technical complications occurred in an isolated pattern, peri-implantitis and implant loss demonstrated clustering with other types of complications.

RESUMO

Objetivo: Presentar la respuesta clínica a largo plazo del tratamiento de un granuloma periférico de células gigantes en un implante oseointegrado en el maxilar inferior. Caso clínico: Un paciente de 60 años, de sexo masculino, sin antecedentes sistémicos, concurrió por una lesión con márgenes definidos, de color rojizo morado y consistencia blanda sobre los tejidos blandos en la cara vestibular de un implante colocado en zona de 46. Se realizó la escisión quirúrgica de la lesión, se procesó el tejido extirpado y se envió al laboratorio. El estudio anatomopatológico confirmó el diagnóstico de granuloma periférico de células gigantes. La lesión recidivó dos veces. En la tercera extirpación se realizó la implantoplastía de la superficie del implante. La cicatrización no presentó inconvenientes. Hasta el último control, a los 5 años, no volvió a haber recidiva. Conclusión: En este caso clínico, se logró mantener la salud periimplantaria durante 5 años luego de la eliminación de un granuloma periférico de células gigantes. No obstante, este tuvo que ser removido en tres oportunidades debido a la alta recidiva (AU)


Aim: To evaluate the long-term clinical response to the treatment of a peripheral giant cell granuloma in an osseointegrated implant in the lower jaw. Clinical case: A 60-year-old male patient, with no systemic medical problems, presented a soft tissue lesion located at the buccal aspect of an implant placed in the 46 area. The lesion had defined reddish-purple margins and soft consistency. Surgical excision of the lesion was performed, processed and sent to the laboratory. The histopathology confirmed the diagnosis of peripheral giant cell granuloma. The lesion recurred twice. During the third surgical removal an mplantoplasty of the implant surface was performed. The healing was uneventful and there was no recurrence until the last control at 5 years. Conclusion: In this clinical case, perimplantar gingival health was maintained for 5 years after the surgical removal of a giant cell peripheral granuloma. However, it had to be removed three times, demonstrating a high recurrence (AU)

RESUMO

OBJECTIVES: Risk prediction in implant dentistry presents specific challenges including the dependence of observations from patients with multiple implants and rare outcome events. The aim of this study was to use advanced statistical methods based on penalized regression to assess risk factors in implant dentistry. MATERIAL AND METHODS: We conducted a retrospective study from January 2016 to November 2018 recording postoperative complications including bleeding, hematoma, local infection, and nerve damage, as well as early implant failure. We further assessed patient- and implant-related risk factors including smoking and diabetes, as well as treatment parameters including types of gaps and surgical procedures. Univariable and multivariable generalized estimating equation (GEE) models were estimated to assess predictor effects, and a prediction model was fitted using L1 penalized estimation (lasso). RESULTS: In a total of 1,132 patients (mean age: 50.6 ± 16.5 years, 55.4% female) and 2,413 implants, postoperative complications occurred in 71 patients. Sixteen implants were lost prior to loading. Multivariable GEE models showed a higher risk of any complication for diabetes mellitus (p = .006) and bone augmentation (p = .039). The models further revealed a higher risk of local infection for bone augmentation (p = .003), and a higher risk of hematoma formation for diabetes mellitus (p = .007) and edentulous jaws (p = .024). The lasso model did not select any risk factors into the prediction model. CONCLUSIONS: Using novel methodology well-suited to tackle the specific challenges of risk prediction in implant dentistry, we were able to reliably estimate associations of risk factors with outcomes.

RESUMO

Eye globe rupture with consequent enucleation is an extremely rare complication of orbital infection spreading from maxillary sinusitis related to dental implant surgery. We report a case of orbital abscess leading to rupture of the globe of the eye in a 60-year-old woman with acute unilateral maxillary sinusitis after dental implant surgery on the left maxillary alveolar bone. The patient had uncontrolled diabetes. Despite surgical intervention, infection of the maxillary sinuses spread to the ocular area, causing disastrous results. To our knowledge, this entity has not been reported previously.

RESUMO

Numerous randomised controlled multicentric studies have investigated various responses to different treatment modalities with dental implants. These studies do not always show the results of daily practice as they are performed under controlled and strict clinical conditions. This multicentric, non-interventionist trial aimed to document the behaviour of implants when used in daily dental practice, without inclusion or exclusion criteria. One hundred and ninety-six screw-shaped, tissue-level implants were placed, and each clinician decided which implant, surgical loading and prosthetic protocol to use. At surgery, data related to the implants were recorded. Additionally, the crestal bone level changes were evaluated for up to two years of follow-up. Two implants were lost before they were loaded. The success rate was 98.31%, and the survival rate was 98.79%. The implant stability quotient (ISQ) at surgery was 68.61 ± 10.35 and at 2 years was 74.39 ± 9.64. The crestal-shoulder distances were 1.25 ± 1.09 mm and 1.68 ± 1.07 mm in the mesial and distal aspects on the day of surgery, respectively, and 2.04 ± 0.91 and 2.16 ± 0.99 mm at 2 years, respectively. At 2 years, 69.3% of the patients were highly satisfied. The use of implants under standard conditions seemed to have success rates similar to their placement in controlled studies.
