Alveolar Ridge Augmentation with Titanium Mesh. A Retrospective Clinical Study

Abstract

An adequate amount of bone all around the implant surface is essential in order to obtain long-term success of implant restoration. Several techniques have been described to augment alveolar bone volume in critical clinical situations, including guided bone regeneration, based on the use of barrier membranes to prevent ingrowth of the epithelial and gingival connective tissue cells. To achieve this goal, the use of barriers made of titanium micromesh has been advocated.A total of 13 patients were selected for alveolar ridge reconstruction treatment prior to implant placement. Each patient underwent a tridimensional bone augmentation by means of a Ti-mesh filled with intraoral autogenous bone mixed with deproteinized anorganic bovine bone in a 1:1 ratio. Implants were placed after a healing period of 6 months. Panoramic x-rays were performed after each surgical procedure and during the follow-up recalls. Software was used to measure the mesial and the distal peri-implant bone loss around each implant. The mean peri-implant bone loss was 1.743 mm on the mesial side and 1.913 mm on the distal side, from the top of the implant head to the first visible bone-implant contact, at a mean follow-up of 88 months.The use of Ti-mesh allows the regeneration of sufficient bone volume for ideal implant placement. The clinical advantages related to this technique include the possibility of correcting severe vertical atrophies associated with considerable reductions in width and the lack of major complications if soft-tissue dehiscence and mesh exposures do occur.

Guided bone regeneration: materials and biological mechanisms revisited

“…The use of titanium for GBR was inspired from a successful outcome of using a titanium mesh for reconstruction of maxillofacial defects . Several studies have shown that using a titanium mesh alone or with bone substitutes is an effective procedure for localized alveolar ridge augmentation prior to, or simultaneously with, implant placement . Occlusive titanium and micro‐perforated titanium membrane have also been introduced and used for treatment of peri‐implant bone defects and ridge augmentation .…”

The Role of Strontium Enriched Hydroxyapatite and Tricalcium Phosphate Biomaterials in Osteoporotic Bone Regeneration

“…For example, Herford et al found that addition of recombinant human bone morphogenetic protein type 2 to a collagen matrix, which is applied during distraction osteogeneis, increases faster bone tissue regeneration [5]. Poli et al also reported that guided BTE, using titanium micromesh filled with bone grafts, provides sufficient bone volume correction in humans with severe alveolar atrophies [6]. Furthermore, clinical study by Chen et al found an increase of bone healing and good bone to implant incorporation when biphasic calcium phosphate ceramics were used as a local treatment for comminuted fractures and fracture nonunion [7].…”

Alveolar Ridge Reconstruction with Titanium Meshes and Simultaneous Implant Placement: A Retrospective, Multicenter Clinical Study

“…Several clinical studies have demonstrated that titanium meshes can promote the formation of new bone, when positioned before [19–24] or simultaneously with dental implants [25–27]. …”
