Study Overview
Brief Summary
This study will compare clinical and radiographic outcomes of three different treatment modalities for atrophied distal extension maxillary ridges these modalities include
- Implant retained distal extension RPD
- Sinus lift and long implant and screw-retained prosthesis
- Short implant and screw-retained prosthesis
Detailed Description
Patient selection:
For this study, 60 patients were selected from the clinic of Prosthodontic Department, Faculty of Dentistry, Mansoura University.
Inclusion criteria:
The patients will be selected according to the following:
- They have distal extension maxillary ridge with sinus pneumatization and remaining alveolar bone height 6- 8mm as verified by preoperative CBCT, have no previous denture experience. They are healthy, free from any systemic diseases relating to the bone resorption (diabetes - hyperparathyroidism). This can be achieved through medical history and clinical examination by a physician and laboratory investigations.
- Posterior maxillary alveolar ridge deficient in height, width and covered with healthy firm mucosa.
- Patients are less satisfied with conventional RPD.
- Absence of maxillary sinus diseases. Exclusion criteria

Outcomes
Primary Outcomes
Plaque index
Time Frame: one year
measuring plaque accumulation around implants using scores
Gingival index
Time Frame: one year
measuring gingival inflammation around implants using scores
Marginal bone loss
Time Frame: one year
measuring crestal bone loss around implants in mm
Probing depth
Time Frame: one year
measuring peri-implant probing depth in mm
implant stability
Time Frame: one year
measuring the mobility of the implants using resonance frequency analysis Implant stability quotient)
Patient satisfaction using VAS questionnaire (visual analogue scale)
Time Frame: one year
Regarding VAS, participants were asked to score their answer according to the amount of satisfaction on a 100mm line (Score zero = no satisfaction at all and score 100 = complete satisfaction). The questions cover several items related to prosthesis such as: retention, stability, comfort, ease of cleaning, ease of speaking, ease of chewing, limited activities due to embarrassment, quality of bolus and appearance.
Secondary Outcomes
- Muscle activity(one year)
- Prosthetic Aspects(one year)
- maximum bite force(one year)
