Details and patient eligibility

About

The aim of the study was to assess the clinical and radiographic outcomes of crestal sinus lifting using densah burs versus lateral window technique in vertically deficient posterior maxilla with simultaneous implant placement.

Enrollment: 14 patients

Sex: All

Ages: 18 to 55 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• 1. Patient medically free from systemic, immunologic or debilitating diseases or local conditions that could affect normal bone healing and/or implant placement.

  2. Patient with good oral hygiene. 3. Age from 18 to 55 years. 4. Partially edentulous patients with missed one or more of maxillary posterior teeth with residual alveolar ridge height 3-5 mm and a minimal width of the alveolar ridge 7 mm in the region of the planned implant site.

  5. Patients' edentulous ridges covered with optimal width of keratinized mucosa (<3 mm) with no signs of inflammation, ulceration of scar tissue.

  6. No history of parafunctional habits. 7. Patients were ready to comply with the follow-up and maintenance program. 8. Sufficient inter arch space for prothesis.

Exclusion criteria

- 1. Patients with clinical or radiographic evidence of rhinosinusitis or any other pathology in the maxillary sinus.

2. Smokers. 3. Pregnancy.

crestal technique using densah burs

Experimental group

Description:

Seven implant sites underwent sinus membrane elevation procedure using densah burs with crestal approach. Crestal flap was made and Densah bur with diameter 2.00 mm will be used in osseodensification mode with copious irrigation till sinus floor, then diameter 3.00 mm bur up to 3 mm past the sinus floor, then sequential wider burs to reach the final desired width followed by bone grafting and simultaneous implant placement.

Treatment:

Procedure: crestal sinus lifting using densah burs

lateral window technique

Active Comparator group

Description:

Seven implant sites underwent sinus membrane elevation procedure using lateral window technique. Pyramidal flap was made and an trap door is created in the lateral sinus wall to gain access to Schneiderian membrane in order to elevate it and provide space for the bone graft material to be placed followed by simultaneous implant placement.

Treatment:

Procedure: sinus lifting using lateral window technique
