Graftless TSFE Via Self-tapping Implants

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.

Inclusion criteria

• Adults aged 18-80 years.
• Patients with edentulous posterior maxilla.
• Residual bone height approximately 4-6 mm.
• Indicated for transcrestal sinus membrane elevation.
• Good general health (ASA I or II).
• Ability to provide written informed consent.
• Willingness to attend follow-up visits.

Exclusion criteria

• Severe systemic diseases (ASA III or above).
• Uncontrolled diabetes mellitus.
• Active sinus pathology.
• History of radiotherapy in the head and neck region.
• Heavy smokers (>10 cigarettes/day).
• Pregnancy or lactation.
• Untreated periodontal disease.
