Maxillary Sinus Lift With and Without Self-hardening Biphasic Calcium Phosphate.

Maxillary Sinus Lift With and Without Self Hardening Biphasic Calcium Phosphate and Simultaneous Implant Placement

This study was carried out to compare the outcome of sinus lift without grafting material, versus the use of moldable, self hardening calcium phosphate biomaterials with simultaneous implant placement.

This study was designed as a randomized controlled clinical trial, the study population consisted of 20 patients with missing maxillary posterior teeth and residual bone height 5-7mm. The sample was selected conveniently according to a list of inclusion and exclusion criteria, the participants were allocated randomly into two equal groups. All patients had sinus lift using piezosurgery device with simultaneous implant placement. In group I, blood clot was the only filling material. In group II, moldable, self-hardening calcium phosphate was the filling material. Clinical and radiographic evaluations were done through 6 months postoperatively.

Inclusion Criteria:

• Patients having missing posterior maxillary teeth
• The vertical height between the floor of the maxillary sinus and the alveolar crest ranged between 5 and 7mm,
• Free from maxillary sinus pathologies
• Adequate oral hygiene
• Acceptable interarch space for the prosthesis

Exclusion Criteria:

• Patients with systemic diseases that directly affect the surgical procedure and/ or the healing of the bone
• immunocompromised status
• Alcoholism
• psychiatric disorders
• Parafunctional habits
