Trephine Osteotomy in Lateral Sinus Lift

Hams Hamed Abdelrahman14 enrolled

Overview

Trephine osteotomy was used for lateral sinus lifting technique associated with sinus floor augmentation using the autogenous bone resulting from implant drilling using specialized trephine drills.

The study includes 14 patients in whom the lateral sinus lift technique was performed using the trephine osteotomy with simultaneous implant placement. Sinus floor augmentation with autogenous bone graft resulting from implant site preparation with trephine drills. Implant stability and rate of complications such as Schneiderian membrane perforation and bleeding will be assessed. Patients will also provide their subjective assessment of postoperative pain and swelling. Vertical bone height, that will be gained, will be assessed radiographically

Interventions

Trephine osteotomyPROCEDURE

* Using a trephine on a straight implant handpiece (at approximately 1800 rpm) with copious irrigation to avoid overheating the bone, a round bone cut will be made 4 -5 mm above the crest of the alveolar ridge. * The trephine is positioned perpendicular to the lateral wall, removing the outer cortex with a very gentle touch to avoid tearing the schneiderian membrane.

Inclusion Criteria: * Patients of both genders requiring implant placement in the posterior maxilla. * Age between 20-50 years. * Tooth extractions at the implant sites were performed at least 4 months before surgery. * Residual bone height between the alveolar bone crest and the sinus floor ranges from 4 to 6 mm. * Patients who are willing and fully capable to comply with the study protocol Exclusion Criteria: * Maxillary sinus pathologies (sinusitis, long standing nasal obstruction) * Any disease contraindicating surgery (e.g. uncontrolled diabetes) * Heavy smokers * Acute oral infections * Poor oral hygiene * A history of radiotherapy or chemotherapy of the head and neck region

Outcomes

Primary Outcomes

Change in Implant stability

This will be measured by implant stability meter (OsstellTM)

Time frame: at baseline and 6 months

change in bone density

Panoramic radiography will be performed immediately postoperatively and cone beam computed tomography (CBCT)

Time frame: at baseline, 3rd and 6th months

change in bone volume

Panoramic radiography will be performed immediately postoperatively and cone beam computed tomography (CBCT)

Time frame: at baseline, 3rd and 6th months

change in bone vertical bone height

Panoramic radiography will be performed immediately postoperatively and cone beam computed tomography (CBCT)

Time frame: at baseline, 3rd and 6th months

Secondary Outcomes

post operative pain

This will be assessed using a 10-point Visual Analogue Scale (VAS) in the 1st week postoperatively. (0-1=None, 2-4=Mild-Moderate, 8-10= Severe)

Time frame: after 1 week

Postoperative edema

* None (no inflammation). * Mild (intraoral swelling confined to the surgical field). * Moderate (extraoral swelling in the surgical zone). * Severe (extraoral swelling spreading beyond the surgical zone

Time frame: after 1 week
