Implant Placement

Several techniques have been proposed for bone regeneration in patients with atrophic ridges. Nowadays, GBR represents the gold standard, and it allows obtaining sufficient bone volumes for a correct implant-prosthetic rehabilitation. Our goal is to perform a systematic review of the literature on the use of titanium meshes in GBR in order to evaluate the reliability of the procedure, the regeneration obtained, and the failures. Furthermore, we will evaluate the success and survival rate of the inserted implants. The selected articles concern vertical and/or horizontal regeneration of the alveolar ridge using titanium grids, in association or not with biomaterials, before and simultaneously with implant placement. Six articles were selected for the present review, including a total of 139 patients, 156 sites, and 303 implants. Titanium grids in combination with autogenous bone were used in 2 cases, 5 in combination with a mixture of autogenous bone and bone substitutes. The overall survival and success rates of implants were 98.3% and 85.25%, respectively. In conclusion, our review shows how the use of titanium mesh represented a predictable method for the rehabilitation of complex atrophic sites.

ABSTRACT Aim The present work describes a horizontal ridge augmentation in which a titanium mesh was preshaped by adapting it to a stereolithographic model of the patient's jaw that was fabricated from CT scans. Background Guided bone regeneration (GBR) involves covering the augmentation site with a long-lasting barrier to protect it from the invasion of surrounding soft tissues. Among barriers, titanium meshes may provide a successful outcome, but the intraoperatory time needed to shape them is a disadvantage. Case description The 54-year-old patient, missing the right mandibular second bicuspid, first molar, and second molar, had her atrophic ridge augmented with a 30:70 mixture of autogenous bone and equine, enzyme-deantigenic collagenpreserved bone substitute. Two conical implants were inserted concomitantly in the second bicuspid and first molar positions, and the site was protected with the preshaped mesh. Four months later, the titanium mesh was retrieved, a bone sample was collected, and histological and histomorphometric analyses were performed. Provisional and definitive prostheses were then delivered, and follow-up controls were performed for up to 24 months. Conclusion Preshaping the mesh on a model of the patient's mandible shortened the surgical time and enabled faster mesh placement. Two years after surgery, the implants were perfectly functional, and the bone width was stable over time as shown by radiographic controls. Histological analysis of the bone sample showed the heterologous biomaterial to be biocompatible and undergoing advanced remodeling and replacement with newly formed bone. Clinical significance Preshaping a titanium mesh over a stereolithographic model of the patient's jaw allowed for a significant reduction of the intraoperative time and may be therefore, advisable in routine practice.

Objetivo: Esta revisão sistemática avaliou a influência do tipo de membrana (colágeno reabsorvível ou politetrafluoretileno expandido não reabsorvível; e-PTFE) na regeneração óssea guia associada à colocação do implante. Métodos: Qualquer tipo de estudo clínico ou revisão de literatura foi pesquisada nas bases de dados MEDLINE / PubMed e Cochrane. Dois revisores independentes examinaram títulos / resumos de artigos e o texto completo de estudos potencialmente elegíveis. Quando os dados estavam disponíveis, a meta-análise pareada foi realizada usando modelo estatístico aleatório. Resultados: Nove estudos preencheram os critérios de inclusão, considerando 685 implantes em 360 pacientes. A regeneração óssea vertical não diferiu com o uso das duas membranas em 8 dos 9 estudos incluídos. Meta-análise não mostrou maior ganho ósseo vertical ou perda óssea vertical após a regeneração com qualquer uma das membranas. Os resultados mostraram uma tendência de maior ganho ósseo na regeneração óssea guiada horizontal com membranas de e-PTFE não reabsorvíveis (relatadas por 2 de 3 estudos). Todos os estudos mostraram claramente que ambas as membranas foram eficazes no aumento do volume ósseo. Não houve uma tendência clara de qualquer uma das duas membranas em causar mais complicações. Conclusão: o colágeno reabsorvível e as membranas não-reabsorvíveis de PTFE-e são igualmente eficazes na regeneração óssea guiada vertical; no entanto, a regeneração óssea guiada horizontal parece se beneficiar com o uso das membranas não reabsorvíveis. Ambas as membranas mostraram-se eficazes na regeneração óssea guiada e similares em relação às complicações.

Bone Gain

The presence of satisfactory bone volume is fundamental for the achievement of osseointegration. This systematic review aims to analyse the use of titanium meshes in guided bone regeneration in terms of bone gain, survival and success rates of implants, and percentages of exposure. An electronic search was conducted Articles were selected from databases in MEDLINE (PubMed), SCOPUS, Scielo, and Cochrane Library databases to identify studies in which bone regeneration was performed through particulate bone and the use of titanium meshes. Twenty-one studies were included in the review. In total, 382 patients, 416 titanium meshes, and 709 implants were evaluated. The average bone gain was 4.3 mm in horizontal width and 4.11 mm in vertical height. The mesh exposure was highly prevalent (28%). The survival rate of 145 simultaneous implants was 99.5%; the survival rate of 507 delayed implants was 99%. The success rate of 105 simultaneous implants was 97%; the success rate of 285 delayed implants was 95.1%. The clinical studies currently available in the literature have shown the predictability of this technique. It has a high risk of soft tissue dehiscence and membrane exposure although the optimal management of membrane exposition permits obtaining a sufficient bone regeneration volume and prevents compromising the final treatment outcome.

Hba1c Levels

Diabetes represents a challenge in implant therapy because hyperglycemia may negatively affect bone regeneration, directly compromising clinical outcomes and increasing clinical failures. The aim of this retrospective study is to analyse the prognostic significance of HbA1c levels in patients undergoing implant placement associated with horizontal guided bone regeneration. Thirty-four patients were divided into 3 groups according to their HbA1c levels: nondiabetic normoglycemic patients ( HbA 1 c < 5.7 % ), nondiabetic hyperglycemic patients ( HbA 1 c < 6.5 % ), and controlled diabetic patients ( HbA 1 c < 7 % ). Primary outcomes were dimensional changes in height (VDH) and width (DW) of the peri-implant defect. Secondary outcomes were evaluations of periodontal parameters of adjacent tooth sites, wound healing, marginal bone loss (MBL), and survival and success rates. At T 1 (6 months), mean VDH values in groups 1, 2, and 3 were, respectively, 0.07, 0.5, and 0.25 mm. Mean DW values in those same groups were, respectively, 0.07, 0.38, and 0.33 mm. HbA1c levels were not statistically related to VDH and DW values at T 1 . No statistically significant differences were observed in MBL between groups ( p = 0.230 ). Implant survival and success rates were, respectively, 98% and 96%. Simultaneous guided bone regeneration is a feasible procedure for the treatment of horizontal bone deficiencies in controlled diabetic patients.

Abstract Guided bone regeneration (GBR) is a therapeutic modality to achieve bone regeneration with the use of barrier membranes. The use of deproteinized bovine bone material (DBBM) for ridge preservation allows the preservation of the edentulous ridge dimensions. Here, we present a case of horizontal GBR using DBBM and a resorbable membrane, with simultaneous implant placement. Simultaneously, ridge preservation of the pontic area, using DBBM within a “socket seal” procedure was performed. Two implants were places at sites 23 and 26 to support a fixed partial denture (FPD). The mesial implant showed exposed buccal threads, which were then covered with autogenous bone particles and small size granules of DBBM. The collagen membrane was stabilized with periosteal mattress suture. Six months postoperatively, CBCT images revealed a stable buccal bone layer at the implant site, indicating a successful GBR procedure. At this point in time, tooth 24 was atraumatically extracted. A ridge preservation was done utilizing DBBM, and a soft tissue graft form the tuber. A ceramic-metal FPD with excellent “white aesthetics” and a harmonic transition zone to the soft tissue was fabricated. At 3 years follow up, the peri-implant bone levels were stable, and the clinical outcomes were excellent. It is concluded that a GBR procedure, utilizing DBBM and a collagen barrier membrane with simultaneous implant placement, as well as ridge preservation using DBBM, are predictable therapeutic methods. However, gentle manipulation of the soft tissues, and wound stability, with tension-free passive closure of the wound margins are prerequisites for a long-term clinical success.

Post-extraction crestal bone resorption is common and unavoidable which can lead to significant ridge dimensional changes. To regenerate enough bone for successful implant placement, Guided Bone Regeneration (GBR) is often required. GBR is a surgical procedure that uses barrier membranes with or without particulate bone grafts or/and bone substitutes. There are two approaches of GBR in implant therapy: GBR at implant placement (simultaneous approach) and GBR before implant placement to increase the alveolar ridge or improve ridge morphology (staged approach). Angiogenesis and ample blood supply play a critical role in promoting bone regeneration.
