RESUMO

PURPOSE: Simplified and predictable immediate single-tooth replacement therapy can be optimised by leveraging recent advances in digital workflows that combine static surgical guidance and customised prosthesis design and fabrication. The present case report illustrates a novel approach to successfully executing immediate single-tooth replacement therapy via static computer-aided immediate implant placement and digital provisionalisation utilising angulated screw access, with a 1-year follow-up after delivery of the definitive restoration. MATERIALS AND METHODS: A healthy 27-year-old woman with congenital agenesis of the mandibular second premolars and who required replacement of the mandibular left second premolar underwent immediate single-tooth replacement therapy via computer-aided, restrictive implant placement and provisionalisation using custom prosthetic components designed prior to the surgical intervention being performed. RESULTS: After a 6-month healing period, the provisional crown was replaced with the definitive restoration. After 1 year, the peri-implant keratinised mucosa demonstrated vertical gain in the mid-buccal portion and stability in the interproximal aspects, and no changes in marginal bone level were observed. CONCLUSIONS: The present case report demonstrates the successful application of novel digital tools to facilitate both surgical and prosthetic aspects of immediate single-tooth replacement therapy. Digital workflows can optimise the clinical efficiency and predictability of tooth replacement therapy with dental implants by reducing surgical and restorative chair time and increasing patient satisfaction.

RESUMO

The tilted implantation technique is characterized by placing the implant at an angle of more than 15° and less than 45° from the horizontal plane. This technique can avoid damaging the maxillary sinus, inferior alveolar nerve, nasal base, and other anatomical structures when the height of the upper and lower jaw available bone is insufficient, to maximize the use of available bone and avoid a large range of bone increment. The tilted implantation technique can reduce the trauma of the surgery, increase the possibility of immediate restoration and shorten the treatment cycle, which has been widely used clinically. In this review, the scope of application, design elements, design scheme and complications of the tilted implantation technique for edentulous patients will be described.

RESUMO

The correct implant site design and placement are the basic clinical techniques that must be known for implant restoration. For a long time, most implants have been placed by free hands, and the choice of site is mostly dependent on the accumulation of long-term experience of the surgeon. The selection of implant site guided by this experience analogy logic is often based on the surgeon's level of experience,which often makes it very easy to produce complications related to the implant restoration of the incorrect site. In contrast, a clinical program using digital guidance and real-time measurable verification has emerged based on the restoration-oriented implantation concept, which marks the formation of an accurate, measurable and verifiable whole-process digital implant prototype. Furthermore, from the perspective of surveying, the numerical requirements that digital implant restoration relies on are actually incomplete to the four elements of measurement, which leading to the doubts about its authenticity. This article will question the numbers in implant restoration, and conduct a preliminary demonstration, and propose a new reliable actual measurement and verification method of the correct location and the numerical requirements of the restoration space and a new clinical program that relies on numbers from the perspective of the evolution of digital restoration, guided implantology and actual measurement technology. And this article further discusses the current mainstream implant restoration technology based on experience analogy which cannot effectively support the whole process of digital implant restoration and provides a new logical cognitive basis for the final realization of the entire process of digital implant restoration.

RESUMO

AIM AND OBJECTIVE: Evaluation and comparison of insertion torque (IT) and the implant stability of two different implant macrogeometry in different bone densities using resonance frequency analysis. MATERIALS AND METHODS: A total of 48 implants (with two implant types having regular and novel macrogeometry) were classified into 4 groups with 12 samples in each group. Group A regular implant without surface treatment, group B regular implant with surface treating, group C novel implant deprived of surface treating, and group D was new dental implant with surface treatment were used. Implant stability quotient (ISQ), implant IT, removal torque (RT) percentage, and torque reduction percentage were calculated. RESULTS: The mean ± SD ISQ value of bone 1 in group A was 56.7 ± 3.2, in group B was 58.6 ± 2.4, in group C was 57.1 ± 3.5, and in group D was 59.3 ± 2.9. In bone 2, the value was 57.8 ± 1.4, 59.5 ± 1.5, 58.2 ± 2.6, and 59.5 ± 2.4 among A, B, C, and D groups correspondingly. In bone 3, it was 59.4 ± 2.4, 60.3 ± 2.3, 60.4 ± 2.8, and 62.7 ± 2.5 among A, B, C, and D groups correspondingly. In bone 4, it was 67.2 ± 3.4, 69.5 ± 2.7, 68.7 ± 2.4, and 69.4 ± 2.3 among A, B, C, and D groups correspondingly. There was a substantial difference in IT and nonsignificant difference in RT in different groups. CONCLUSION: There was a low IT value with new implant macrogeometry as compared to regular implant macrogeometry. There was absence of association between IT and implant stability. CLINICAL SIGNIFICANCE: Calculation of torque insertion score helps in implant placement. Higher bone density scores produce a higher option of decreasing the initial torque. Low IT of new implant types is useful to reduce failure.

RESUMO

PURPOSE: The aim of this systematic review with meta-analysis was to compare the survival rate of single crowns supported by extra-short implants (≤ 6 mm) to those supported by conventional implants, with or without previous maxillary sinus augmentation. The proportion of failures was described according to the type of complication and follow-up periods. MATERIALS AND METHODS: Randomized and prospective clinical trials were selected from six databases and gray literature. The risk of bias was evaluated by Joanna Briggs Institute Critical Appraisal Checklist, and the certainty of the evidence was analyzed with Grading of Recommendations Assessment, Development, and Evaluation. Meta-analyses were processed with RevMan and MedCalc Statistical Software. RESULTS: Single crowns supported by extra-short implants had a similar risk of failure to those supported by conventional implants, regardless of previous maxillary sinus augmentation (P > .05). Overall failure proportion of extra-short implants was 5.19%, but it varied according to follow-up (1.18% before loading, 1.56% at 12 months, 1.20% at 24 months, 2.10% at 48 months). Biologic failure complications were 37.90% for bleeding on probing, 22.45% for peri-implantitis, and 11.29% for infection. Prosthodontics failure complications were 14.88% for abutment failures and 14.73% for prosthetic screw loosening. Considering the risk of bias, most studies were classified at moderate risk. CONCLUSION: The risk of failure of single crowns supported by extra-short implants is similar to those supported by conventional implants, regardless of previous maxillary sinus augmentation or follow-up period. The most frequent biologic and prosthetic complications were bleeding on probing and abutment failures, respectively.

RESUMO

PURPOSE: To analyze the effect of implant placement and loading protocols (protocol types) on the survival of single implant tooth replacements in different locations. MATERIALS AND METHODS: An electronic search was conducted to identify clinical trials regarding outcomes of single implants subjected to different treatment protocols. A weighted mean survival rate for each protocol type in the anterior maxilla, anterior mandible, posterior maxilla, and posterior mandible was calculated. Study design, sample size, and outcome homogeneity were used to evaluate the validation of each protocol type in different locations. RESULTS: A total of 45 publications (13 RCTs, 21 prospective studies, and 11 retrospective studies) were included. The anterior maxilla was the most reported site (35 studies, 1,391 implants, weighted survival rate: 97.5% to 99.6%). Immediate placement + conventional loading (Type 1C) and late placement + immediate restoration/loading (Type 4A) were scientifically and clinically validated (SCV). For the posterior maxilla (19 studies, 567 implants, weighted survival rate: 85.7% to 100%), Type 1C was SCV. The anterior mandible was the least-reported site (three studies, 42 implants, weighted survival rate: 98.5% to 100%). For the posterior mandible (13 studies, 447 implants, weighted survival rate: 95.0% to 100%), late placement + conventional loading (Type 4C) was SCV. It was not possible to perform a metaanalysis due to the limited number of controlled studies that had the same comparison and considerable heterogeneity in study design. CONCLUSION: Differences were found in the level of scientific evidence between the anterior and posterior and the maxilla and mandible, indicating that location is a consideration when selecting treatment protocol for a single implant.

RESUMO

PURPOSE: This study evaluated the long-term survival and success rates of dental implants placed with autogenous onlay block bone grafts harvested from the mandibular ramus. MATERIALS AND METHODS: Patients treated with onlay bone graft from the mandibular ramus due to a severe vertical alveolar defect from 2001 to 2017 were included in this study. The marginal bone loss, success, and survival time of the implants were recorded and analyzed with clinical factors, such as time from bone graft to implant placement, type of implant prosthesis connection, history of periodontitis, and insertion depth. RESULTS: Seventy-five implants in 40 onlay bone-grafted areas of 38 patients were included, with a mean follow-up period of 102 months (range: 14 to 192 months). Two grafts were removed before implant placement. Of the 75 implants, 11 implants were lost. History of periodontitis and marginal bone loss at 6 months after implant placement were significantly associated with implant success. The receiver operating characteristic curve showed that a marginal bone loss of 0.75 mm after 6 months of implant placement was related to implant success, with a sensitivity of 72.2% and specificity of 89.6%. CONCLUSION: Implants placed with onlay bone graft from ramal bone had more frequent biologic complications, and failures may be predicted by measuring the amount of implant bone loss after 6 months of placement.

RESUMO

PURPOSE: The aim of this study was to investigate the influence of different clinical parameters on the primary stability of a variable thread tapered implant system with a focus on surgical undersizing protocols. MATERIALS AND METHODS: This retrospective study evaluated patients who received NobelActive implants in a single institution. The relationship between the independent variables, bone quality, implant diameter, implant length, implantation time, region of the jaw, and surgical undersizing protocol, and the dependent variable, maximum insertion torque, was investigated. Statistical analysis was conducted using analysis of variance (ANOVA) and multiple linear regression. RESULTS: A total of 1,292 implants placed in 574 fully or partially edentulous patients were evaluated. For the total sample size, without further differentiation between bone qualities, statistically significantly higher primary stability values were shown for an 8% to 9% undersized group (50.33 ± 17.16 Ncm), compared with a 16% undersized group (41.88 ± 17.63 Ncm), a 20% undersized group (33.65 ± 15.78 Ncm), a 26% to 28% undersized group (34.53 ± 15.49 Ncm), and a 35% to 44% undersized group (32.78 ± 18.80 Ncm). No statistical differences were found for undersizing protocols in bone quality 4. Bone quality had the highest influence on primary stability (Welch-Test F(3, 65.57) = 119.48, P < .001, η2 = .20). Contrary to the other investigated independent variables, no statistically significant differences in primary stability were found for the different implantation times. CONCLUSION: Undersizing protocols exceeding 8% to 9% do not seem to enhance primary stability values. Further studies are needed to investigate the biologic consequences of undersizing, including the impact of implant design characteristics.

RESUMO

PURPOSE: The study aimed to evaluate the outcomes of flapless guided surgery related to surgery, patient, operator, assistant, and advisor, comparing it with conventional surgery performed by undergraduate students who had never placed implants in patients. MATERIALS AND METHODS: A randomized controlled split-mouth clinical trial was carried out. Ten patients with bilateral mandibular posterior tooth loss received an implant on each side with conventional flap surgery or flapless guided surgery that was performed by undergraduate students. Surgery time, pain, patient satisfaction, quantity of consumed medications, time of procedure, ease of procedure, anxiety, and stress were assessed. RESULTS: Conventional surgery showed statistically significantly inferior results compared with flapless guided surgery in terms of procedure time (56 minutes, 36 seconds ± 8 minutes, 38 seconds vs 30 minutes, 1 second ± 6 minutes, 2 seconds), consumption of analgesic medications (49 tablets vs 15 tablets), intraoperative (1.75 ± 1.56 vs 0.65 ± 0.64) and postoperative pain (4.62 ± 2.17 vs 1.17 ± 0.72), and operator anxiety (4.76 ± 1.66 vs 3.47 ± 1.50), respectively. CONCLUSION: Flapless guided implant surgeries performed by individuals with no previous clinical experience showed reduced surgery time and delivered better patient-reported outcomes both in the intraoperative and postoperative periods; reduced medication consumption; and showed better results in the operator and assistant perspectives.

RESUMO

PURPOSE: This study aimed to investigate the influence of oversized drilling on the stability of the implant and the bone response during osseointegration. MATERIALS AND METHODS: The trial was designed as a prospective, parallel-group randomized controlled clinical trial with 20 implants placed in the posterior region of the maxilla. The sample size was divided into two groups, 10 each, with implants being placed with manufacturer-recommended implant osteotomy preparation according to the manufacturer guidelines in one group (MR group) vs oversized osteotomy preparation (3 to 5 mm) in the other group (oversized drilling [OD] group). The implant stability was monitored for 3 months by means of resonance frequency analysis, while the crestal bone levels were recorded using parallel technique periapical radiography for 6 months. Patient-reported outcomes including pain, swelling, satisfaction, and implant survival were all monitored throughout the study. RESULTS: In the MR group, a mean decrease in implant stability quotient (ISQ) values was detected during the first 4 weeks, after which a gradual increase in values was recorded. In comparison, the OD group showed a rapid increase in ISQ value over the entire follow-up period from baseline and up to week 12. Regarding crestal bone level, follow-up showed a significant difference when comparing baseline and 6-month radiographs (P = .00) between the OD group, 0.908 mm ± 0.343, and the MR group, 1.3 ± 0.23 mm. CONCLUSION: Within the limitations of this study, the results suggest that the oversized osteotomy technique may lead to earlier implant stability and postsurgical recovery compared with the manufacturer-recommended technique for osteotomy preparation. However, further studies are needed to confirm these findings.

RESUMO

PURPOSE: The aim of this split-mouth randomized clinical trial was to evaluate the primary and secondary stability of implants with hydrophilic surfaces in comparison to implants with conventional surfaces in the posterior region of the maxilla. MATERIALS AND METHODS: Twenty patients with a bilateral edentulous ridge in the posterior area of the maxilla randomly received implants with two types of surfaces: (1) implants with the surface modified by double acid-etching and sandblasting (DAS, n = 20); and (2) implants with the surface modified by double acid-etching and sandblasting, stored in 0.9% saline solution to confer highly hydrophilic properties (DAS-H, n = 20) on the surface. The implants presented the same macrostructure with a hybrid design. The resonance frequency analysis was performed in order to obtain the implant stability quotient (ISQ) using Osstell. The ISQ analyses were performed just after placement of the implant (primary stability) and at 28, 40, and 90 days after the surgical procedure (secondary stability). RESULTS: There were no differences between the DAS and DAS-H surfaces in the primary stability or during the conversion of the primary to the secondary stability; however, there was a reduction in the stability of the implants at 28 days, which increased significantly at 40 and 90 days in both surfaces. CONCLUSION: It can be concluded that the surface wettability of implants with a hybrid macrostructure did not increase the primary and secondary implant stability in the posterior region of the maxilla.

RESUMO

PURPOSE: This cross-sectional study aimed to identify and characterize the pathway for appropriate placement of four zygomatic implants in the severely atrophic maxilla and to group the anatomical variations of the osteotomy trajectory for anterior zygomatic implants. MATERIALS AND METHODS: CBCT images of patients presenting indications for the use of four zygomatic implants to withstand a maxillary rehabilitation were reviewed. Cross-sectional planes corresponding to the implant trajectories, designed according to a zygoma anatomy-guided approach for implants placed in the anterior and posterior maxilla, were assessed separately. The relationship of the implant osteotomy trajectory with the correlated residual alveolar bone, nasal and sinus cavities, maxillary wall, and zygomatic bone anatomies was established. RESULTS: The study population included 122 globally recruited patients, with 488 zygomatic implants, 244 of which had their starting point on the anterior incisor-canine area and 244 on the posterior premolar-molar area. The anatomy of the osteotomy path designed for the anterior implants ("A") was named and grouped into five assemblies from zygomatic anatomy-guided ZAGA A-0 to A-4, representing 2.9%, 4.5%, 19.7%, 55.7%, and 17.2% of the studied sites. Percentages for posterior implant ("P") trajectories of the osteotomy were grouped and named as ZAGA P-0 to P-4, representing 5.7%, 10.2%, 8.2%, 18.4%, and 57.4% of the sites, respectively. Approximately 70% of the population presented anatomical intra-individual differences. CONCLUSION: The trajectory of the zygomatic implant followed different anatomical pathways depending on its coronal point being anteriorly or posteriorly located, which justifies a new zygoma anatomy-guided approach classification for anteriorly placed zygomatic implants. Topographic characteristics of the anatomical structures that are cut by an anterior oblique plane joining the lateral incisor-canine area to the zygomatic bone, representing the planned anterior osteotomy path in a quadruple-zygoma indication, have not been previously reported. Adaptation of surgical procedures and implant sections/designs to individual patients' anatomical characteristics is essential to reduce early and long-term complications.

RESUMO

The use of 3-dimensional imaging and guided surgery applications for implant dentistry has increased profoundly in the past several years. New technology has evolved to increase surgical speed and enhance patient comfort and care. Dynamic guided navigational surgery has improved dental implant surgery, enabling placement accuracy that compares favorably to traditional static guides. This article describes the benefits and improvements that guided navigational surgery provides, including efficient workflow, real-time feedback, enhanced access and visualization, and the ability to execute on-demand directional changes. Additionally, two clinical cases are presented that illustrate the use of dynamic navigation.

RESUMO

Contemporary dental implant therapy has flourished in recent years thanks in large part to advances made in bone augmentation capabilities. Bone grafts, which are often crucial to the success of implant restorations, are used mainly in three instances: at the time of extraction for delayed implant placement, when an immediate-socket implant is placed, and for ridge augmentation either laterally or vertically. Many bone grafting options are available to the surgeon depending on the site to be treated and the requirements in the area. Bone grafts and barriers come from different sources and are seen by the body's cell types in different manners. This yields a variety of biological outcomes, some of which have been published while others are in the process of being studied.

RESUMO

OBJECTIVES: Evaluate the dimensions and morphology of peri-implant tissues around a modified dental implant designed with tissue level connection and a convergent transmucosal neck, when compared with a conventional bone level implant connected to a cylindrical machined titanium abutment. MATERIAL AND METHODS: Eight experimental animals were used for this in vivo investigation, in whom 16 test and 16 control implants were placed following a random allocation sequence. The following histological outcomes at 4 and 12 weeks were evaluated: morphology of peri-implant tissues, the soft tissue height and thickness, the horizontal and vertical bone remodeling, and the bone to implant contact (BIC). RESULTS: In both early (4 weeks) and late (12 weeks) healing times, there were no statistically significant differences between test and control implants, with respect to the overall height and thickness of the peri-implant hard and soft tissues. There was a tendency toward a more coronal free gingival margin (I-FGM) at the buccal aspect of test when compared to control implants (at 4 weeks, difference of 0.97 mm (p = .572) and 0.30 mm (p = 1.000) at 12 weeks). Similarly, there was a tendency toward a more coronal position of the first bone to implant contact (I-B) at the buccal aspect of test as compared to control implants (1.08 mm (p = 0.174) at 4 weeks and 0.83 mm (p = 0.724) at 12 weeks). CONCLUSIONS: Hard and soft tissue healing occurred at both implant types with no statistically significant differences. Test implants tended to present a more coronal gingival margin (FGM) and first bone to implant contact (B).

RESUMO

One serious complication in implant surgery is displacement of the implant body into the surrounding tissue. This occurs only rarely in the mandible, however. This report describes a case of an implant body displacing into the medullary cavity of the mandible and discusses this in reference to the literature. The patient was a 72-year-old woman who was referred to our department at Tokyo Dental College Chiba Hospital (now Chiba Dental Center) by her regular dentist after an implant inserted in the left mandible in 2010 showed loosening in October 2016. Panoramic X-rays obtained at the initial examination revealed that 2 implants had been inserted into the left mandible, one on top of the other. Removal of both was recommended to prevent infection at the implant site and any potential effects on the alveolar nerve. In the absence of subjective symptoms other than implant loosening, however, the patient did not consent to this proposal. Therefore, only the broken abutment was removed. The patient was instructed to contact us immediately should infection or any other symptoms appear once the mucosa had healed, and the dental clinic that had referred her to us was requested to make her a set of dentures. To our knowledge, only 11 reports have been published to date describing displacement of an implant body into the mandible, and these address a total of just 20 cases. The possibility that an implant body in the mandible may become displaced must be kept in mind during treatment.

RESUMO

OBJECTIVES: To summarize the clinical performance of anodized implants connected to different prostheses design after immediate/early (IL) or conventional loading (CL) protocols. MATERIALS AND METHODS: Seven databases were surveyed for randomized (RCTs) and non-randomized controlled clinical trials (CCTs). Studies comparing IL vs. CL protocol of anodized implants supporting single crown, fixed partial denture (FPD), full-arch fixed dental prosthesis (FDP), or overdenture were included. Risk-of-bias was evaluated using Cochrane Collaboration tools. Meta-analyses for different follow-up were analyzed, followed by heterogeneity source assessment and GRADE approach. The outcomes included implant survival rate, marginal bone loss (MBL), implant stability quotient (ISQ), probing depth (PD), plaque index (PI), and peri-implantitis prevalence. RESULTS: From 24 eligible studies, 22 were included for quantitative evaluation. Most RCTs (58%, n = 11) and all the 5 CCTs had high and serious risk-of-bias, respectively. Overall, pooling all prosthesis design, no difference between IL vs. CL protocols was observed for all outcomes (p > .05). However, according to prosthesis type subgroups, CL reduced MBL for full-arch FDP (p < .05). In a point-in-time assessment, with overdenture, although IL presented higher PI (12 months), it showed lower MBL (≥24 months), higher ISQ (3 months), and lower PD (6 and 12 months) (p < .05). Conversely, PD was higher for IL in single crown (3 and 6 months) (p < .05). Regarding MBL, IL demonstrated higher mean difference for full-arch FDP (36 months) and FPD (12 and 36 months) (p < .05). CONCLUSION: Within the limitations of this study, overall, there is no significant difference in the outcomes between IL and CL loading protocols.

RESUMO

A Odontologia atual apresenta relevantes mudanças no processo de reabilitação oral. Com isso, a instalação de implantes osseointegrados, constituem uma importante ferramenta neste âmbito, pois permitem a devolução da função mastigatória, permitindo também que os pacientes tenham a estética recuperada. O presente trabalho tem como objetivo realizar uma revisão de literatura, sobre a importância de um planejamento prévio, chamado também de planejamento reverso, o mesmo aponta um maior sucesso no processo reabilitador, apresentando-se como uma técnica que busca facilitar e estudar a correta reabilitação do paciente, proporcionando uma melhor previsibilidade para o tratamento, a partir do momento em que se planeja a reabilitação oral protética antes mesmo de se pensar no processo cirúrgico de implantes osseointegrados. Conclui-se com esse trabalho que o sucesso do tratamento com implantes depende diretamente de um prévio plano de tratamento, independentemente da extensão da área edêntula, quando é realizado um planejamento reverso diminuiu-se a taxa de intercorrências, além de aumentar a taxa de sucesso no processo de reabilitação(AU)


Current Dentistry presents relevant changes in the oral rehabilitation process. As a result, the installation of osseointegrated implants is na important tool in this context, as it allows the return of lost teeth, also allowing patients to have their function and aesthetics recovered. For greater success of the rehabilitation process, reverse planning presents itself as a technique that seeks to facilitate the correct rehabilitation of the patient, allowing better predictability for the treatment from the moment that the prosthetic oral rehabilitation is planned before even thinking about the surgical process of osseointegrated implants. The success of treatment with implants depends directly on a properly planned treatment plan, regardless of the extent of the edentulous area. This paper aims to conduct a literature review on the importance of reverse planning in implantology(AU)

RESUMO

O objetivo deste estudo é realizar uma revisão da literatura para identificar os principais fatores que levam às complicações em implantodontia. Os implantes osseointegráveis e sua aplicação na odontologia revolucionaram a reabilitação oral de pacientes sejam eles edêntulos totais ou parciais em busca de recuperação funcional e satisfação estética. A pesquisa científica em uma busca constante pela magnificação deste tratamento, possibilitaram o uso de reabilitações implantossuportadas como um método de tratamento previsível com um índice elevado de sucesso. No entanto, como qualquer modo de tratamento, complicações e falhas também podem ocorrer na implantodontia. Após a revisão de literatura pode-se concluir que as condições médicas do paciente, hábitos sociais e parafuncionais, inexatidão do planejamento cirúrgico e protético, conhecimento técnico e científico do cirurgião-dentista, a falta de relacionamento interdisciplinar e deficiente cooperação do paciente no pós-operatório, podem estar relacionadas às complicações no tratamento reabilitador com implantes dentários(AU)


The objective of this study is to carry out a complete literature review to elucidate and evaluate the factors that lead to complications in implantology. The osseointegrated implantsimplants and their application in dentistry have revolutionized the oral rehabilitation of patients who need this treatment, be they total or partial edentulous in search of functional recovery and aesthetic satisfaction. Scientific research and a constant search for the magnification of this treatment, allowed the use of implant-enhanced rehabilitation as a predictable treatment method with a high success rate. However, like any treatment mode, complications and failures can also occur in implantology. the patient's medical conditions, social and parafunctional habits, inaccuracy of surgical and prosthetic planning, technical and scientific knowledge of the dental surgeon, lack of interdisciplinary relationship and poor patient cooperation in the postoperative, may be related to complications in rehabilitating treatment with dental implants(AU)
