Edentulous Alveolar Ridge In Mandible
Conditions
Brief summary
This study aims to compare clinical outcomes and tissue stability at implant sites in the mandibular posterior region with insufficient buccal keratinized gingiva. It will assess the use of free gingival grafts either before or during the second stage of implant surgery.
Detailed description
To compare the clinical outcomes and the differences in hard and soft tissue stability at implant sites with insufficient buccal keratinized gingiva in the mandibular posterior region, where free gingival grafts are applied either before implant surgery or concurrently during the second stage of implant surgery.
Interventions
PROCEDUREfree gingival grafts during the second stage of implant surgery
Free gingival graft surgery performed simultaneously with implant stage II, followed by upper restoration 6-8 weeks later.
PROCEDUREfree gingival grafts prior to the implantaion
Free gingival graft surgery performed 6-8 weeks before implant placement
