The aim of this study is to evaluate anatomical considerations and assess the volume of the maxillary sinus bone graft. There were sixty-three patients (eighty-three sinuses) who had taken CT scans for implant surgery. Patients included those whose height of the residual alveolar bone was less than 5 mm. The position of posterior superior alveolar artery, the thickness of the maxillary sinus wall, and the volume of the maxillary sinus according to the amount of sinus floor elevation were measured. The mean vertical distance of posterior superior alveolar artery was 11.91 ± 4.79 mm from 3.03 mm to 24.05 mm. The mean thickness of the lateral wall was 1.71 ± 0.55 mm in the range of 0.74 mm to 3.93 mm. The volume of 3 mm, 5 mm, 7 mm, and 10 mm from the sinus floor was 0.173 ± 0.11 cm3, 0.526 ± 0.25 cm3, 1.068 ± 0.43 cm3, and 2.184 ± 0.74 cm3 on average, respectively. The knowledge of the posterior superior alveolar artery position, the lateral wall thickness, and the volume of the maxillary sinus can help the clinician for sinus bone graft.

Insufficient bone volume is a common problem encountered in the rehabilitation of the edentulous posteriormaxilla with implant?supported prostheses. Although adequate bone height can be achieved using variousmaxillary sinus augmentation techniques, these procedures have been practiced successfully. However,significant complications occur such as perforations or tearing. To maintain the integrity of Schneiderianmembrane subsequently increasing the success rate a retrospective analysis is carried out on varioustechniques with complications which occur during and after treatment. This review will help the readers tounderstand the intricacies of sinus augmentation by using direct techniques.

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.

This case report discusses osteotome sinus floor elevation (OSFE) and immediate placement in 2 stages in severely resorbed alveolar bone height in which multiple implant placement is not otherwise feasible due to a lack of initial stability. The first implant placed using OSFE without bone grafting prepares the adjacent resorbed sites for further implant placement in the sinus areas, which allows for better initial stability and early functional loading. This process avoids the conventional extensive lateral approach for sinus lifting and bone grafting procedures even in extremely resorbed alveolar bone.

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.

Abstract Background The volume of residual alveolar bone is critical to the survival of dental implants. When the volume of alveolar bone in the posterior maxillary region is less than 4 mm, maxillary sinus floor elevation (MSFE) with the lateral approach is an effective option. Traditionally, this standard approach is usually conducted at 4–6 months after tooth extraction (standard MSFE). However, defective dentition due to extraction can impair mastication during the period of bone remodeling, especially if the molars on both sides are severely compromised and must be extracted. MSFE before extraction (modified MSFE) can take full advantage of residual tooth strength. However, the effectiveness and practicability of the modified MSFE procedure remain unknown. Therefore, the aim of this study was to compare the clinical outcomes of modified vs. standard MSFE, in order to provide references to periodontists. Methods/design The study cohort included 25 adult patients (50 surgery sites) recruited from Peking University Hospital and School of Stomatology who met the inclusion criteria. The two sides of each patient will be randomly divided into two groups: a test group-modified MSFE or a control group-standard MSFE. The surgical duration and patient-reported outcomes (visual analog scale for discomfort) will be documented. Clinical indicators, including implant survival rates, mucosal conditions, and complications, will be recorded every 6 months during the 5-year follow-up period. The volume of the alveolar bone and marginal bone level will be assessed radiographically (cone-beam CT and periapical films) every 6 months. Histological analysis of biopsy samples retrieved from both sides will be performed to evaluate the biological features of the bone. Discussion The current study will explore the implant survival rates, safety, reliability, effectiveness, and practicability of the modified MSFE procedure. Moreover, the extent of osteogenesis on the sinus floor will also be assessed. The results of this trial will provide strategies for the modified MSFE procedure to achieve ideal clinical outcomes.

The most recently reported techniques for the rehabilitation of the atrophic posterior maxilla are increasingly less invasive, as they are generally oriented to avoid sinus floor elevation with lateral access. The authors describe a mini-invasive surgical technique for short spiral implant insertion for the prosthetic rehabilitation of the atrophic posterior maxilla, which could be considered a combination of several previously described techniques based on the under-preparation of the implant site to improve fixture primary stability and crestal approach to the sinus floor elevation without heterologous bone graft. Eighty short spiral implants were inserted in the molar area of the maxilla in patients with 4.5–6 mm of alveolar bone, measured on pre-operative computed tomography. The surgical technique involved careful drilling for the preparation of implant sites at differentiated depths, allowing bone dislocation in the apical direction, traumatic crestal sinus membrane elevation, and insertion of an implant (with spiral morphology) longer than pre-operative measurements. Prostheses were all single crowns. In all cases, a spiral implant 2–4 mm longer than the residual bone was placed. Only two implants were lost due to peri-implantitis but subsequently replaced and followed-up. Bone loss values around the implants after three months (at the re-opening) ranged from 0 to 0.6 mm, (median value: 0.1 mm), while after two years, the same values ranged from 0.4 to 1.3 mm (median value: 0.7 mm). Clinical post-operative complications did not occur. After ten years, no implant has been lost. Overall, the described protocol seems to show good results in terms of predictability and patient compliance.

Abstract Background Residual alveolar bone volume is a critical factor for the dental implants’ survival [1]. When the volume of alveolar bone in the posterior maxillary region is less than 4mm, the maxillary sinus floor elevation (MSFE) with lateral approach is an effective way to solve this problem [2]. Traditionally, this standard approach is usually delivered 4 months after the extraction of the tooth. However, the defective dentition due to the extraction would cause impaired masticatory function during the long period of the bone regeneration, especially when molars on both sides are severely periodontal compromised and need to be extracted. So, as periodontists, we start to wonder if we can maintain a compromised tooth so that we perform the sinus floor elevation before the extraction (the modified MSFE) to take fully advantage of residual strength of the teeth. Methods/Design The proposed study is designed as a prospective single-center, split-mouth design, randomized controlled trial. We plan to recruit 10 patients whose molars on both sides are severely periodontal compromised and in need of dental implant treatment in the atrophied posterior maxilla. The two sides of each patients will be divided into two groups randomly using Randomizer for Clinical Trials (Institute for Medical Informatics, Statistics and Documentation, Medical Univ. Graz). Test group: sinus floor augmentation before tooth extraction (the modified MSFE); Control group: sinus floor augmentation after tooth extraction (the standard MSFE). Implant survival rates, mucosal conditions around the implants, complications, treatment time and postoperative discomfort (visual analogue scale for intraoperative pain and postoperative pain/discomfort) will be recorded. The volume of the alveolar bone will be measured 6, 12, 18, and 24 months after the MSFE surgery by means of CBCT. Histological and histomorphometic analysis will be performed on biopsies retrieved from both side of grafting sites. Discussion The current study will explore the effectiveness of the modified MSFE on minimizing the discomfort period caused by defected dentition. To determine whether the modified MSFE will promote the grafting outcomes, the quality and the quantity of the osteogenesis on the sinus floor will also be compared. Depending on the result of the current study, we will determine all the protocols and details about the modified MSFE, including indications, detailed methods, post-operational complications and managements.

Clinical and radiological outcomes of one and two stage maxillary sinus floor augmentation with HAP granules and dental implant insertion, degree of mineralization of residual bone and augmented sinus part were evaluated. 180 dental implant insertions in 84 patients in the age from 32-68 years were included in this study. Patient clinical and CBCT (Cone Beam Computer Tomography) were analyzed by quantitative radiodensitometry using HU (Hounsfield units) after 1 to 5 years after functional loading. Four implants were lost during osseointegration phase the 176 implants survived. We found 2.5 times denser synthetic HAP/bone area comparing with residual bone. With time there was a decrease in radiodensity in HAP augmented maxillary sinus area and an increase of radiodensity in the area of residual alveolar bone.
