RESUMO

La osteomielitis focal esclerosante es un cuadro de poca frecuencia ante el cual no existen demasiadas opciones terapéuticas, al margen del tratamiento de conductos del diente afectado. En caso de no encontrarse el diente vital, los tratamientos se reducen y, respecto del hueso afectado, no existen evidencias científicas sobre la colocación de implantes. Presentamos un caso clínico en el que se maneja este cuadro eliminando el hueso y regenerándolo con PRGF-Endoret®, para colocar posteriormente un implante dental. (AU)


Focal sclerosing osteomyelitis is a rare condition with few therapeutic options other than root canal treatment of the affected tooth. If the tooth is not vital, the treatments are reduced, and there is little scientific evidence of the benefits of the placement of implants in the affected bone. We present a clinical case in which this condition is managed by removing the affected bone, regenerating it with PRGF-Endoret® and subsequently placing a dental implant in the treated area. (AU)

RESUMO

OBJECTIVE: A nasal septal abscess after placement of a dental implant is seldom seen and is usually caused by an infection around the implant. A septal haematoma following dental implantation leading to septal abscess formation has never been reported. METHODS AND RESULTS: We present a case of a patient who developed a septal abscess after dental implantation without accompanying signs of infection around the implant. On the computed tomography scan we found the implant protruding the nasopalatine duct which led to bilateral septal hemorrhage, resulting in abscess formation. The patient underwent reconstructive nasal septum surgery, using an autologous auricular cartilage graft. This resulted in a good nasal function and cosmetic outcome. CONCLUSIONS: Medical health care professionals should be aware of a septal abscess in case of an acute blocked nose even without prior nasal or facial trauma or nasal surgery. Reconstruction of the septal nasal cartilage using autologous conchal cartilage is a good solution to preserve nasal function as well as tip support.

RESUMO

OBJECTIVES: A randomized clinical trial was conducted to compare all three known static guided surgery protocols (pilot, partial, and full) with each other and with freehand surgery in terms of accuracy, under the same conditions. MATERIAL AND METHODS: A total of 207 implants of the same brand and type were placed in 101 partially edentulous volunteers in need of implantation in the mandible or maxilla or both. All cases were digitally planned, and the comparison of the planned and actual implant positions was performed using a medical image analysis software with dedicated algorithms. The primary outcome variable was angular deviation (AD, degrees). The secondary outcome variables were coronal global deviation (CGD, mm), apical global deviation (AGD, mm), and voxel overlap (VO, %). RESULTS: AD showed stepwise improvement in significant steps as the amount of guidance increased. The highest mean AD (7.03° ± 3.44) was obtained by freehand surgery and the lowest by fully guided surgery (3.04° ± 1.51). As for the secondary outcome variables, all guided protocols turned out to be significantly superior to freehand surgery, but they were not always significantly different from each other. CONCLUSIONS: As for the comparison that this study sought to perform, it can be said that the static guided approach significantly improves the accuracy of dental implant surgery as compared to freehand surgery. Furthermore, the results suggest that any degree of guidance yields better results than freehand surgery and that increasing the level of guidance increases accuracy.

RESUMO

OBJECTIVES: Preoperative maxillary sinus imaging findings have been suggested to be associated with complications and outcomes of sinus lift and dental implant procedures; nonetheless the evidence is controversial. The aim of this study was to examine the association between preoperative maxillary sinus imaging findings and outcomes of sinus lift and dental implant procedures in asymptomatic patients. METHODS: We included all patients who underwent maxillary sinus lift and dental implant procedures between 2014 and 2017. Maxillary sinus imaging findings were extracted from pre-procedural dental computed tomography scans, and outcomes of the procedures were assessed. RESULTS: A total of 145 procedures were included. No sinonasal symptoms were reported preoperatively. In 46% of cases maxillary sinus imaging was abnormal. The most common imaging finding was peripheral mucosal thickening (38%). Sinus floor cyst/polyp was identified in 13% of the cases, of which 47% occupied more than 50% of the sinus volume. Partial or complete opacification of the maxillary sinus was documented in 3% of cases. The sinus ostium and ostiomeatal complex were obstructed in 7% and 1%, respectively. Mucosal perforation was documented in 22% of cases and was inversely related to mucosal thickening (P = 0.011). Other minor post-operative complications did not correlate with radiological findings. Post-surgical sinusitis was not observed in any of the patients regardless of pre-surgical imaging findings. CONCLUSIONS: Incidental maxillary sinus imaging findings such as mucosal swelling, cysts or polyps, regardless of their severity or size, and maxillary ostial obstruction may not need to be addressed prior to sinus augmentation and dental implant procedures in asymptomatic patients. Patients with complete sinus opacification should be referred to an otolaryngologist prior to surgery. Further controlled trials, in larger cohorts, are needed to corroborate our findings.

RESUMO

Prosthetic rehabilitation in patients undergoing reconstructive surgery using vascularized free flaps is challenging, and functional rehabilitation of the patient with a fixed prosthesis is rare. Virtually planned maxillofacial reconstruction including simultaneous dental implantation according to the prosthodontic ideal position of the implants could further enhance dental rehabilitation. The data of 21 patients undergoing fibula free flap reconstructive surgery with CAD/CAM patient-specific reconstruction plates during the years 2015-2018 were analysed, including the applicability of the virtual plan, flap survival, duration of surgery, ischemia time, simultaneous dental implantation, implant exposure, and postoperative complications. The virtual plan could be translated to surgery in all cases. In total, 76 dental implants were simultaneously placed during primary reconstruction in the 21 patients. For 38.1% of these patients, the implants could be uncovered in secondary surgery; the mean duration until exposure was 7.6 months. The implant survival rate was 97.4% (74/76). Wound infection requiring a secondary intervention occurred in 23.8% of patients during follow-up. Virtually planned reconstruction with a fibula free flap, simultaneous dental implantation, and CAD/CAM plates allows early and functional dental rehabilitation. A dental workflow should be integrated into the virtual planning, and prosthetically favourable implant positions should determine the position of the fibula segments.

RESUMO

El objetivo del presente trabajo es la presentación de un caso clínico en el que mostramos dos técnicas quirúrgicas para resolver la atrofia ósea en sentido horizontal. En la implantología actual nos enfrentamos cada vez con más frecuencia a casos con extremas reabsorciones óseas que nos obligan a implementar distintas técnicas quirúrgicas para lograr el éxito de nuestros tratamientos con implantes dentales. La coexistencia de atrofias verticales y horizontales complica la resolución de estos casos con éxito, aunque cada vez con mayor frecuencia nos enfrentamos a este tipo de situaciones más complicadas debido a que los pacientes demandan el tratamiento implantológico incluso en casos muy severos. Por ello, no es infrecuente tener que utilizar técnicas como la expansión de cresta o los implantes cortos de forma combinada en algunas situaciones. En el siguiente caso clínico mostramos una paciente con reabsorción extrema mandibular en ambos sectores posteriores con los dos tipos de reabsorción descritos anteriormente: las zonas posteriores con reabsorción extrema vertical y un abordaje con implantes cortos y una zona anterior con reabsorción extrema horizontal tratada con Split en dos fases mediante implantes expansores transicionales


The objective of this work is the presentation of a clinical case in which we show two surgical techniques to solve the horizontal bone atrophy. In the advanced implant dentistry, different surgical techniques would be required for the successfull treatment of patients presenting severe alveolar ridge atrophy. The presence of vertical and horizontal atrophies increases drastically the difficulty of the clinical case where several surgical techniques will be needed. Therefore, it is not uncommon to performe techniques like the alveolar ridge expansion and short implants in the same mandible or maxilla. The following clinical case presented an advanced horizontal and vertical alveolar atrophy in the right and left posterior regions of the mandible. The treatment plan included the use of short implants to treat the vertical atrophy and the two-stage alveolar ridge split to treat the horizontal atrophy

RESUMO

Antecedentes: La técnica de elevación de suelo del seno maxilar con osteótomos (OSFE) consiste en la realización de un lecho en la cresta ósea por don-de se despega y eleva la membrana de Schneider usando los osteótomos con el fin de colocar implantes de una manera menos invasiva, reduciendo el tiempo de la cirugía y disminuyendo las molestias postoperatorias. Hay diferentes factores a la hora de realizar la técnica, como es la cantidad de hueso residual que posee el maxilar atrófico o el tipo de injerto que se va a situar en el seno. El objetivo principal es evaluar la tasa de supervivencia de los implantes colocados de manera simultánea en maxilares atróficos de ≤ 5 mm RBH (hueso residual) y sin colocación de injerto en la cavidad sinusal. Material y métodos: El estudio consiste en una revisión sobre la realización de elevaciones crestales ≤ 5 mm de hueso residual sin el uso de injertos. Para ello hemos analizado 7 estudios, 2 RCT (en-sayos clínicos aleatorizados), 3 estudios retrospectivos y 2 estudios prospectivos. Resultados: Se produjeron 24 perdidas de implantes, siendo 17 tempranas (antes del año) en 379 implantes colocados. Obteniendo tasas de supervivencia de entre 91,4% al 100% en los respectivos estudios analizados. La pérdida ósea marginal del grupo injerto y grupo no injerto era similar. La ganancia ósea sinusal era mayor en el grupo injerto que en el grupo no injerto. Conclusiones: La tasa de supervivencia de la elevación crestal con colocación simultánea de implantes ≤ 5 mm de hueso residual sin colocación de injerto, mostró ser un tratamiento seguro y eficaz, aunque se necesitan más estudios al respecto


Background: The osteotome maxillary sinus floor elevation technique (OSFE) consists in the realization of a bed at the top of the ocean where the Schneider’s membrane is detached and raised using the osteotomes in order to place implants in a lesser invasive manner, reducing the time of surgery and reducing postoperative discomfort. There are different factors when performing the technique, such as the amount of residual bone that has the maximum flow type or the type of injection that will be placed in the breast. The main objective is to evaluate the survival rate of implants placed simultaneously in atrophic maxillae of ≤ 5 mm RBH (residual bone) and without graft placement in the sinus cavity. Material and methods: The study consists of a systematic review approach on the performance of crestal elevations ≤ 5 mm of residual bone without the use of grafts. This analysis is based on 7 studies, 2 RCT (randomized clinical trials), 3 retrospective studies and 2 prospective studies. Results: There were 24 implants lost, 17 in the short-term (prior to a year) from the 379 implants placed. Obtaining survival rates of between 91.4% to 100% for the cases analyzed. The marginal bone loss of the injected group and non-injected group was similar. Sinus bone gain was greater in the group that participated in the non-graft group. Conclusions: The survival rate of crestal elevations with the simultaneous placement of implants ≤ 5 mm of residual bone was a safe and effective work, although greater detailed investigations are required

RESUMO

BACKGROUND: Dental implantation has become widespread for esthetic and functional rehabilitation following single tooth loss as a preferred alternative to conventional tooth-supported restorations. The main advantage of dental implant placement is that it does not require the preparation of the adjacent sound teeth. OBJECTIVES: The aim of this cohort study was to assess the effect of dental implantation on the hard and soft tissues around the adjacent natural teeth. MATERIAL AND METHODS: In this historical cohort, 34 'connect-type' TBR® implants (bone level), 4 mm in diameter, were submerged in the intact bone of 22 patients (7 males and 15 females). The intraoral and extraoral clinical examination as well as periapical radiography were carried out preoperatively or right after surgery (baseline), at 3 months postoperatively (the time of prosthetic delivery), and at 3 and 6 months after prosthetic delivery. The data was analyzed using the Friedman test (due to the non-normal distribution of the data). In case of presence of a significant difference, pairwise comparisons were performed using the post-hoc Wilcoxon test with the Bonferroni correction. All statistical analyses were performed with a 95% confidence interval (CI) using the SPSS for Windows, v. 16.0 software. The p­value <0.05 was considered statistically significant. RESULTS: The distance from the cementoenamel junction (CEJ) of the adjacent teeth to the bone crest significantly increased at different postoperative time points compared to baseline (p < 0.001). The changes in the papillae of the adjacent teeth were also significant at different postoperative time points (p = 0.04). The pocket depth of the adjacent teeth increased, although the value at 3 months postoperatively was not significantly different from the baseline value (p = 0.842). The distance from the implant shoulder to the bone crest of the adjacent teeth significantly increased at different postoperative time points compared to baseline (p < 0.001). CONCLUSIONS: Our results indicate that implant surgery significantly affects the soft and hard tissues around the adjacent natural teeth.

RESUMO

Morphological and immunohistochemical examination was made on 24 gum biopsies obtained from 35- to 60-year-old patients with diagnosis of partial secondary adentia, chronic generalized moderate to severe periodontitis (19 patients), as well as on the biopsy samples from five patients without pathological periodontal changes who underwent dental implantation. Serial paraffin sections were treated with antibodies against Ki-67, VEGF, and SMA. In patients with severe chronic periodontitis, a high proliferative activity of epithelium indicative of hyperplastic changes was observed, as well as a reduced number of the SMA-positive cells and actual absence of the SMA-positive cell couplings associated with the "growth zones" in tissues, which testifies indirectly to a lower tissue regenerative capacity. Hence, before dental implantation, additional anti-inflammatory and pro-regenerative treatment is required.

RESUMO

OBJECTIVE: To evaluate the sinus bone gains after sinus floor elevation procedures with or without grafts when implants were placed simultaneously. METHODS: The research included 26 edentulous patients in the maxillary posterior region, who were divided into 2 different groups according to the sinus lift procedures employed: group of osteotome sinus floor elevation with bone grafts (group A) and group of osteotome sinus floor elevation without bone grafts (group B). The implants were placed simultaneously, and were followed for a period of 30-50 months after sinus floor elevation as routine and then were observed for sinus bone change. RESULTS: There were 27 implants (13 implants for group A and 14 implants for group B) and the following time was 40.23 (36.20, 48.07) months. The residual bone height (RBH) was (6.64±1.21) mm for group A and ( 6.96±1.36) mm for group B; the difference between the two groups was not statistically significant (P=0.459).The sinus bone gain (SBG) when followed was (2.20±1.71) mm for group A, and 1.77 (0.94, 2.05) mm for group B; the difference between the two groups was not statistically significant (P = 0.583). The quality of apical bone around implant apex was divided into 3 categories which were excellent, fine and fair.The quality of apical bone around implant apex was excellent and fine for 9 implants in group A and 8 implants in group B, and the difference between the two groups was not statistically significant (Fisher exact test, P=0.695).The implant apex when followed was (0.09±1.32) mm below the new sinus floor for group A and (0.03±0.91) mm for group B, and the difference between the two groups was not statistically significant (P = 0.898). The SBG for the total was 1.85 (1.10, 2.20) mm. The SBG was statistically significantly only related to the protrusion height of the implant apex (r=0.383, P=0.049). CONCLUSION: Sinus floor elevation procedures with or without grafts can all gain good results. The SBG is related to the protrusion height of the implant apex significantly.

RESUMO

The aim of this study was to analyze the success rate of dental implants and the graft shrinkage rate after vertical ridge augmentation and simultaneous implantation with an allograft bonering. Fifty-one patients (81 augmentations and simultaneous implantations) were included. The bonering technique followed a standardized protocol. The alveolar ridge was prepared using a congruent trephine, and depending on the defect size, an allograft bonering with an outer diameter of 6-7 mm was placed. The height of the bonering was trimmed with a diamond disc to the required length. The average height of vertical augmentation was 5.5 mm. Implants were inserted through the bonering into the native bone of alveolar ridge. After 6 months, dental implants were exposed, and dental prosthetics were placed. Of 81 implants placed with the bonering technique, two failed during a 12-month follow-up, corresponding to a success rate of 97.5%. One year after surgery, the allograft bonering exhibited an average vertical graft shrinkage rate of 8.6%. In conclusion, the allograft bonering technique was associated with a favorable outcome, and in cases with large vertical defects, both treatment time and donor site morbidity could be reduced.

RESUMO

Dynamic navigation (DN) has been used by many fields previously and recently applied to dental implant surgery. DN allows the implant surgeon to evaluate a patient, scan the patient, plan the implant position, and perform the implant surgery in the same day without the delay or cost of fabrication of a static surgical guide stent. The current DN workflow requires (1) cone-beam computed tomography with fiducials, (2) virtual implant planning, (3) calibration, and (4) implant placement in accordance to the 3-D image on the navigation screen. This technology allows for improved precision and accuracy in the placement of dental implants.

RESUMO

The aim of the study was to determine the activity of alkaline phosphatase (AP), tartrate-resistant acid phosphatase (TRAP) and osteocalcin in oral fluid (OF) in patients with dental implants. Dental intraosseous implantation was performed in 164 patients, aged 45 to 60 years (mean age 54.6±4.17 years), 78 (47.6%) males and 86 (52.4%) females. In 75.6% of patients more than 3 teeth were absent. A total of 641 screw intraosseous implants of the MIS system were installed. Studies were performed prior to implant placement, at 7, 14, 21 days and 3 and 6 months. The control group consisted of 20 volunteers of comparable age, 9 (45.0%) males and 11 (55.0%) females. An increased activity of AP and TPAP was revealed, but the activity change of AP in comparison with the control group was not statistically significant. Activity of TRAP in patients before implantation was higher than in controls by 40.5% (p<0.05) in group without complications and by 61.9% (p<0.05) in patients with mucositis. After implantation, the activity of TPAP remained elevated for 6 months, the maximum activity was observed after 14 days and was 3 times higher than at baseline (p<0.01). The amount of osteocalcin increased, especially in the complicated course after the implantation. The highest values of osteocalcin were observed 14 days after implantation. Determination of the activity of TPAP in the OF after implantation can be used as an indicator of the state of bone metabolism.

RESUMO

BACKGROUND: Clinical measures and implant design innovation to improve primary osseointegration and reduce the bacterial contamination of the peri-implant area are intended to reduce the incidence of late inflammatory complications in dental implantation. PURPOSE: To study the effect of nanostructured coating and antiseptic sealant on the outcomes of dental implantation. MATERIALS AND METHODS: Ninety-six individuals were clinically supervised. In the first group (Screw Ti + sealant), a special antiseptic sealant matrix was used; the same sealant was used with nanocoated implants in the second group (Nanocoat + sealant), and the conventional treatment protocol was used in the control group (Screw Ti). Patients were evaluated longitudinally during treatment and rehabilitation phases with clinical examinations, radiography, periodontal pathogen detection, and patient experience surveys. RESULTS: For patients who received a nanocoated implant and an antiseptic sealant (Nanocoat + sealant), relatively better hygienic indices were observed; there was less contamination with periodontal pathogens, bone density remained at the required level, and the overall results of treatment were better. CONCLUSIONS: Using a matrix for sealing the dental implant-abutment interface with a nanostructured surface provides reliable results regarding stable osseointegration and clinical and patient-reported outcomes of treatment success.

RESUMO

BACKGROUND: Management of the full and partially edentulous arch requires an understanding regarding the amount of vertical and horizontal restorative space that is needed for different types of dental implant prostheses. Failure to design a prosthetic construct without considering space issues can result in a rehabilitation with diminished stability, poor esthetics, and inadequate contours. Therefore, available restorative volume must be computed before initiating therapy to ensure proper prosthesis design. TYPES OF STUDIES REVIEWED: The authors searched the dental literature for articles that addressed space requirements for different types of dental implant prostheses and found a few on this subject. RESULTS: The dental literature indicates there is a 3-dimensional hierarchy of restorative space necessary for different types of implant constructs. The minimum amount of vertical space required for implant prostheses is as follows: fixed screw-retained (implant level): 4 through 5 millimeters; fixed screw-retained (abutment level): 7.5 mm; fixed cement-retained: 7 through 8 mm; unsplinted overdenture: 7mm; bar overdenture: 11 mm; and fixed screw-retained hybrid: 15mm. These dimensions represent the minimal amount of vertical rehabilitative space that can accommodate the above implant prostheses. With respect to horizontal space, computations are needed to account for the discrepancy between an implant and tooth position. CONCLUSIONS AND PRACTICAL IMPLICATIONS: Restorative spaces for each type of prostheses are restoration specific and should be considered during treatment planning to facilitate proper case selection and enhance patient satisfaction.
