It creates a challenging situation for the clinician, especially in terms of implant-supported prosthetic rehabilitation. The present case of a 66-year-old female patient presented with an edentulous span of the right mandibular posterior edentulous site with Siebert class I defect. Literature recommended different bone augmentation procedures for such a clinical situation but are associated with a variety of risks and complications too. Adequate alveolar ridge dimensions are a prerequisite to achieve proper osseointegration; Khoury split bone block (KSBB) technique utilizing combination of thin split autogenous bone and bone particles is a popular intervention that is highly recommended in the literature and was executed in this case. Four months postoperatively Densah bur-assisted osteotomy preparation was done under osseodensification mode followed by implant fixture placement w.r.t tooth no. 45,46,47. Three months postimplant placement, insertion buccal site showed a lack of sufficient width of keratinized tissue. Therefore, free gingival grafting (FGG) was executed in order to maintain the peri-implant tissue health at the buccal aspect of tooth no. 45-47 region, followed by prosthetic rehabilitation at 12 months postoperatively. Clinically, peri-implant tissue was healthy, and no marginal bone loss was observed on radiovisual graph evaluation taken at 1.5 years, postoperatively.
