| dc.description | Bone augmentation procedures are usually indicated to allow implant placement in an optimal three-dimensional position to attain long-term function and predictable esthetic outcomes for the later prosthetic restoration1. However, this ideal situation might not be readily achievable due to the changes in bone volume that occur within the first 3 months of tooth loss. In addition, atrophy of the alveolar crest may result from tooth agenesis, dental and maxillofacial trauma, periodontal disease, tooth extractions, tumor surgery, etc. It may take place in the horizontal as well as in the vertical dimension. Therefore, guided bone regeneration (GBR) has been proposed to restore the lost bone volume to accommodate the dental implant prostheses. The factors that are important to the successful outcome of a GBR treatment include: the surgical technique, the occlusion and stability of the barrier, the dimensions of barrier perforations, the tightness of the seal between the barrier and the host bone, the adequacy of the blood supply and the availability of bone- forming cells bone cells are given a protected environment to populate and mature into the functional living bone by excluding epithelial cells and connective tissue through barrier membranes and bone grafts 2. Several different types of membranes have been considered in recent years that facilitate new bone generation and stabilize the underlying bone graft. Space maintaining membranes minimize the risks of the newly formed ridge collapsing or the space being occupied by ingrowing soft tissue. Experimental and clinical studies have been conducted to test bioresorbable and non-resorbable membrane materials, such as polytetrafluoroethylene (PTFE), expanded PTFE (e-PTFE), titanium meshes, collagen3-6 Published studies have shown that both resorbable and non-resorbable membranes effectively prevent soft tissue cells from invading the area of the bone defect and promoting bone regeneration 7-9. However, the use of such membranes for GBR has sometimes been associated with complications, reportedly involving exposure, infection, and collapse – and the non-resorbable types of membrane seem to be applied more often than the resorbable materials, resulting in the need for additional grafting at a later surgical intervention or implant failure. Many reviews have assessed post-surgical complications in patients who underwent horizontal GBR.1, 10-12 This study aims to evaluate the outcomes associated with complications between the titanium mesh group and the titanium-reinforced group; it also assesses the effect on bone gain after the following complication in the ridge augmentation procedure. | |
| dc.description.abstract | Purpose: The aim of this study is to evaluate complications related to the use of Titanium mesh and Titanium-reinforced membrane following ridge augmentation procedures and their effect on bone gain using CBCT measurements Methods: Clinical and CBCT scans were retrieved from subjects who underwent pre-surgical consultation and completed surgical procedures from 2017 to 2021. Measurements were recorded into two groups based on the space maintainer used during ridge augmentation surgeries, titanium mesh (TI-M) and titanium- reinforced (TI-R). Bone gain dimensions at the crest (BG-C) and middle of the ridge (BG-M) were also noted. From the clinical data, the complications analyzed were early exposures of membranes and infections. Results: The mean BG-C with TI-R in sites with complications is 1.155 mm compared to 1.7mm in sites without complications. The mean BG-M with TI-R is 1.118mm compared to 1.830mm in sites without complications. Mean BG-C in sites with TI-M with complications is 0.786 mm compared to 1.7mm in sites without complications. Mean BG-M in TI-M sites with complications is 0.964 mm compared to 1.757mm in sites without complications. Conclusion: Given the constraints of the study, TI-R had slightly better outcomes in mean bone gain compared to the TI-M group at BG-C and BG-M following complications. However, the sample size of the TI-R group was small (n=21) compared to the TI- M group (n=57). | |
