Maxillary Sinus Disease
Conditions
Brief summary
The post-extraction pneumatization of the maxillary sinus often compromises the ability of the maxillary molar to the optimal recipient of dental implants as a consequence of the quantitative reduction of the vertical bone height and the reduced bone quality of the region posterior maxillary segment.
Interventions
PROCEDURESinus lifting
The implant osteotomy will be initiated by pilot drill entries followed by sequential drills via the radiographic stent's sleeves to position the fixtures precisely into the pre-determined recipient sites. The Implant stability quotient (ISQ) will then be measured using an Osstell device after attaching intelligent implant pigs. Finally, the mucoperiosteal flaps will be sutured in place with 4-0 Prolene.

Inclusion criteria
1. Patients of both sexes, with an age range of (25 to 55 years) with unilateral or bilateral edentulous posterior maxillary molar region with \\ vertical residual bone height of (four to six millimeters), a minimal horizontal bone width of six millimeters bone width, acceptable interarch space, and fair inter-jaw anteroposterior, horizontal and vertical relationships. 2. Proper general health and oral hygiene.
Exclusion criteria
1. The presence of sinusitis, local sinus pathosis, or a systemic disease that would affect the final treatment outcomes, bone remodeling process, or maxillary sinus health. 2. Those patients with a history of previous bone graft, sinus lift, or failed implant.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Vertical bone gain | 6 months | baseline and final outcome for measuring both groups' radiographic vertical bone height gain as a primary outcome aided by the (Blue-sky software) identification of four reference points along each implant buccal, palatal, mesial, and distal surface |
| Stability | 6 months | Aided by the Osstell device, the authors will record the (ISQ) readings at implant placement and upon its exposure for prosthetic rehabilitation after six months as a secondary outcome. The mean (ISQ) of the maxillary sinus lift procedure would employ the mean of parallel and perpendicular (ISQ) readings to each implant long axis where one implant is inserted and the mean of the two implant readings when two implants are placed. The numerical data concerning the primary and secondary outcomes will be recorded, scheduled, and submitted for statistical analysis |
