简要总结
Maxillary posterior area is the most challenging site for dental implant placement. Indeed, complex remodeling processes, resulting in changes of the maxillary sinus and shape of the alveolar ridge will cause difficulties in rehabilitating the posterior maxillae sites. Various techniques have been proposed in order to achieve the necessary bone volume for the placement of long term successful implants. However, unbalanced crown to implant ratio remains a risk factor after successful dental implants installation following sinus graft. No study on humans assessed the effect of apical positioning of the implants in posterior grafted sites (sinus graft or sinus graft + vertical GBR) on the following clinical parameters: The peri-implant bone remodeling (vertical bone loss (mm) and probing depth (mm) around the implants, crown bulkiness, emergence profile and crown height, and Patients satisfaction, food impaction (PROM)).
This study will elucidate these points and based on the parameter's results, suggest a treatment based classification facilitating the treatment decision-making of the clinicians in case of an atrophic posterior maxilla; aiming to ensure a long-term successful supra-implant rehabilitation which will maintain its bio-mechanically and biological success.

结局指标
主要结局
peri-implant marginal bone remodeling (mm)
时间窗: 3 years
Recorded at the mesial and distal aspect of each implant. The distance from the implant-abutment interface to the first bone-to-implant contact (bone level) was assessed on peri-apical radiographs taken with the long cone paralleling technique that were taken during the recall visits (after implant loading). Bone Level values were calibrated according to the actual implant length, following the next formula, according to Chen et al. 2023: (99) The BL was measured at the mesial (M) and distal (D) aspects of each implant at baseline (initial bone level, IBL) and follow-up (final bone level, FBL). The change in MBL was calculated as the difference between the mean FBL and mean IBL. The following formulas were used: (99).
- Pocket probing depth (mm).
时间窗: 1 week
is measured with the periodontal probe Hu-Friedy Periodontal Probe PCP UNC15 (Hu-Friedy, Chicago, Illinois), going parallel to the axis of the implant to the nearest 0.5 mm, at 6 different sites per implant (mesiobuccal, buccal, distobuccal, mesiopalatal, palatal, distopalatal)
- Bleeding on probing.
时间窗: 1 week
analyzed 15 seconds following pocket probing around 6 sites per implant.
