What Is the Most Effective Rehabilitation Method for Posterior Maxillas With 4 to 8 mm of Residual Alveolar Bone Height Below the Maxillary Sinus With Implant-Supported Prostheses? A Frequentist Network Meta-Analysis

The bone available for implant placement may be limited by the presence of the maxillary sinus togetherwith loss of alveolar bone height and it may be increased by augmentation. Minimally invasive sinusaugmentation is an effective solution for this problem. This review explains indirect sinus augmentationprocedures which are less invasive and highly successful if done using prescribed technique.

Maxillary Sinus Floor Elevation

Nowadays implant-prosthetic rehabilitations are one of the best solutions for rehabilitating our patients. These allow obtaining rehabilitations with optimal functional and aesthetic performances. Often patients, who undergo implant-prosthetic therapy, have the conditions of edentulias, single or multiple, that have been going on for some time. This, according to the literature, produces resorption of the alveolar bone, a process that is complicated in the posterior area of the upper arch by a pneumatization of the maxillary sinuses. The loss of vertical height, so that the implant fixtures can be inserted, requires a maneuver called maxillary sinus floor elevation. This procedure, now safely performed with piezoelectric instruments, allows increasing bone height through bone grafting. In this study, the tissue obtained from a patient, after 15 years from the intervention, was evaluated by histological and SEM analyses. The bone healing in the patient has led to a perfect integration between the patient’s bone and the fresh frozen allograft used, however still present and detectable after 15 years.

Implant placement on maxillary posterior region has some limitations because of limited bone height, low bone density, and anatomical consideration involving the floor of the maxillary sinus. A 56-year-old male with a history of hypertension and stroke, consulted for edentulous in teeth 25 and 26 with limited bone height. A short implant for 26 (Ø 4.8 mm; 4 mm) and 25 (Ø 4.1 mm; 10 mm) were placed and splint crown was performed after 6 months.

Aim: To evaluate the hypothesis of a correlation between the preoperative residual alveolar bone height (RBH) and graft maturation after maxillary sinus floor augmentation procedures using two different bone substitutes. Methods: A total of 20 patients who underwent unilateral maxillary sinus floor augmentation with either mineralized deproteinized bovine bone (DBBM) or a xenograft enriched with polymer and gelatin (NBS) were included in this prospective study. Six months after sinus surgery, bone biopsies were harvested with a 3.2 mm diameter trephine bur, prior to dental implant placement. Histomorphometric analysis was performed, and the results were correlated with the individual RBH. Implants were loaded after 5 months of insertion, and 1-year implant success and marginal bone level change were assessed. Results: RBH was 2.17 ± 1.11 mm (range 0.5–3.5 mm) and 2.14 ± 0.72 mm (range 0.5–3.0 mm) in the NBS and DBBM group, respectively. The biopsy analyses for the DBBM group showed woven bone increases by 5.08% per 1-mm increment of RBH; medullary spaces decreased by 9.02%, osteoid decreased by 4.4%, residual biomaterial decreased by 0.34%, and lamellar bone increased by 5.68% per 1-mm increase of RBH. In the NBS group, samples showed woven bone increases by 8.08% per 1-mm increase of RBH; medullary spaces decreased by 0.38%; osteoid increased by 1.34%, residual biomaterial decreased by 0.58%, and lamellar bone decreased by 5.50% per 1-mm increase of RBH. There was no statistically significant difference in the correlation between RBH and lamellar bone, woven bone, and osteoid, independently of the material used. Implant success was 100% in both groups, and marginal bone loss was 1.02 ± 0.42 mm in DBBM and 0.95 ± 0.31 mm in the NBS group after the 1-year follow-up. Conclusion: In spite of the absence of significance, the observed trend for woven bone to increase and medullary spaces to decrease when RBH increases deserves attention. Residual bone dimension might be a determinant in the bone graft maturation after maxillary sinus augmentation.

Background: Alveolar bone height in the posterior maxillary region is very important and critical for dental implant planning and placement. Objective: This study aimed to evaluate the anatomy of the maxillary sinus floor in relation to the alveolar crest and to determine variations in the vertical measurements between the maxillary sinus floor and the alveolar bone crest tip in the posterior edentulous maxilla with the use of cone beam computerized tomography. Methods: This analysis enrolled 234 retrospectively selected patients (123 males with mean age 52.95±11.74 (range 32-76 years) and 111 females with mean age 58.14±11.92 (range 32-75 years)) with edentulous posterior maxillary regions. The maxillary sinus floor was divided into three anatomical segments (anterior, median and posterior) in relation to the transverse palatine suture. The measurements were performed on 3D surface rendered volumetric images by using rotation and translation of the views. Landmarks for measurement were specified by using a cursor driven pointer. Vertical lines were marked on the cross-sectional images between the alveolar ridge and the deepest point of the maxillary sinus floor for each of the three regions. P < 0.05 was regarded as statistically significant. Results: The mean distance values between the sinus floor and the alveolar crest in the anterior, median and posterior regions were 8.74±3.97 mm, 5.37±3.23 mm and 7.06±3.28 mm, respectively. Measurements in the anterior region were found to be high in both total and gender groups compared to other regions. Also, subsinus alveolar bone heights decreased with increasing age in both genders in all three regions. Conclusion: This study emphasizes that the mean subsinus alveolar bone height is highest in the anterior segment of the edentulous posterior maxilla. These results may guide clinicians to make the decision of implant placement area and lead to less invasive alternative surgery methods for edentulous posterior segments.
