Brief summary
This prospective clinical trial aims to evaluate the efficiency, safety, and reliability of a minimally invasive graftless transcrestal sinus lifting approach with simultaneous dental implant placement in patients with edentulous posterior maxilla and limited residual bone height. The study investigates bone formation beneath the Schneiderian membrane, implant stability, osseointegration, and long-term implant survival.
Detailed description
This prospective clinical study evaluates a minimally invasive graftless sinus lifting technique using a transcrestal approach with simultaneous implant placement in the posterior maxilla. The procedure involves tenting the Schneiderian membrane without the use of grafting material, relying on blood clot formation and natural bone regeneration beneath the elevated membrane. Radiographic and clinical evaluations will be performed preoperatively, immediately postoperatively, and at 6 months to assess bone formation, implant stability, and osseointegration.
Interventions
PROCEDUREGraftless Transcrestal Sinus Membrane Elevation with Simultaneous Implant Placement
A minimally invasive transcrestal approach for sinus membrane elevation without graft material, followed by simultaneous placement of a 10 mm length and 4-4.5 mm diameter dental implant in the posterior maxilla with residual bone height of approximately 5 mm.

Masking description
This is an open-label single-arm prospective clinical study. No masking will be applied to participants, care providers, investigators, or outcome assessors.
Intervention model description
This is a prospective single-arm clinical study in which all enrolled participants undergo transcrestal graftless sinus membrane elevation with simultaneous dental implant placement. Clinical and radiographic evaluations are performed preoperatively, immediately postoperatively, and at 6 months to assess bone formation and implant stability.
