Dimensional Changes Following Immediate Implant Placement in Molar Extraction Sockets With or Without Bone Graft

Sponsor: Misr International University

Summary

Statement of problem: The majority of studies on immediate implant placement are related to the maxillary esthetic zone. Literature concerning Immediate implant placement in the posterior region is scarce. Furthermore, there is paucity of evidence on alveolar bone dimensional changes following immediate implant placement in fresh extraction sockets of posterior teeth. Adding to that, negligible evidence is known about the soft tissue alterations which take place during modeling and remodeling phases of socket healing process; regarding the molar sites. Nevertheless, Immediate installation into a molar socket raises an extra challenge for the clinicians, because of the different anatomical features of the extraction sockets compared to that of the single-rooted teeth in the anterior zone. In addition to, implant positioning difficulties; due to the amount of the residual inter-radicular bone after extraction. Aim of the study: To assess the bucco-lingual ridge collapse after immediate implant placement in lower 1st molar sites either with customized healing abutment only; or with xenogeneic bone graft and customized healing abutment. Materials and methods: The current study will include 28 non-restorable lower 1st molar teeth indicated for extraction in the posterior area. Patients will randomly be assigned into two equal groups: the test group; Immediate implant placement + customized healing abutment group and the control group; Immediate implant placement +bone graft+ customized healing abutment group. The presented trial will investigate the following outcomes: bucco-lingual ridge collapse as the primary outcome, together with mid-facial recession, total volume gain/loss, buccal soft tissue contour, bucco-lingual bone width, and vertical bone changes as the secondary outcomes after 12 months
