Osseodensifiction Versus Piezoelectric Internal Sinus Elevation Technique in Delayed Implant Placement

Osseodensifiction Versus Piezoelectric Internal Sinus Elevation (PISE) Technique in Delayed Implant Placement (A Randomized Controlled Clinical Trial)

The present study is a parallel single-blinded randomized controlled clinical trial.

The study will be conducted after being reviewed and approved by the Faculty of Dentistry, AinShams University Research Ethics Committee (FDASU-REC).

The study population will be randomly allocated into two groups of the same size:

Group 1: Osseodensifiction sinus lift will be performed using sticky bone as a graft material.

Group 2: Piezoelectric Internal Sinus Elevation (PISE) will be performed using sticky bone as a graft material.

The aim of the present study is to evaluate the effectiveness and clinical results of osseodensification in comparison to Piezoelectric Internal Sinus Elevation (PISE) Technique in Delayed Implant Placement.

Inclusion Criteria:

1. Patient partially edentulous with maxillary posterior edentulous ridge after extraction of more than 4 months.
2. Both sexes will be selected males and females.
3. Adult patients aged between 18 and 40 years of age.
4. Good general health (American Society of Anesthesiology Physical Status Ⅰ-Ⅱ).
5. Initial residual alveolar ridge height ranging between 4 to 6 mm according to preoperative CBCT.
6. No previous surgery or radiation treatment on the maxillary sinus.

Exclusion Criteria:

• 1. Smokers. 2. Pregnant or lactating females. 3. Psychiatric disorders. 4. Uncontrolled systemic disease. 5. Hematologic diseases and coagulation disorders. 6. Chemotherapy or radiotherapy of the head and neck area, and immunocompromised status.

  7. Medical conditions affecting bone metabolism and ongoing treatment with bisphosphonates drugs or systemic steroids.

  8. Presence of acute or chronic sinus pathoses or sinus membrane perforation.
