Introduction: the article presents the results of the outcomes analysis of bone grafting for dental implants, review some technical and biological factors that caused the success in this oral surgery. Also describes the different types of the maxillary sinus floor, «micro-window» technique for sinus-lifting and local bone modifying. This current aims to evaluate clinical outcomes after various bone grafting techniques for dental implan-tation, as well as to analyze the biological success factors of these surgery.Materials and methods: 134 bone grafting surgeries were performed - 23 men and 73 women. The patients were divided into 4 groups according to the methods: Guided Bone Regeneration (GBR); Bone Block (BB) transplantation; micro-window Sinus-lifting (mwSL); Local Bone Modifying (LBM).Results: The operations of the GBR and BB together showed an unsuccessful result in 72.36% of cases, while the bad outcomes of the mwSL and LBM operations were 7.7%. The better results were in groups with mwSL (success in 97.5%) and LBM surgery (87.1%).Conclusion: This demonstrates the clinical importance and effectiveness of various bone grafting methods. GBR and BB are less predictable in success, in contrast to mwSL and LBM, which we recommend. However, the factors affect the success of this surgery require further study.

Maxillary Sinus Floor Augmentation

The aim of this study was to evaluate differences in ossification of the 2 forms of demineralized bone matrix (DBM)—putty and powder—radiographically, using digital densitometry on panoramic radiographs in maxillary sinus floor augmentation procedures. Twelve subjects needing bilateral maxillary sinus floor augmentation for the placement of osseointegrated implants were included in this study. The left and right maxillary sinuses were augmented in the same session in each patient using the 2 preferred forms of DBM—putty and powder—during the same session. One sinus was augmented with DBM putty form and the other sinus was augmented with DBM powder form randomly. Every patient had a total of 4 panoramic radiographs taken, preoperatively and in the first, third, and sixth month postoperatively. The densitometry measurements were taken from each step of the aluminium step-wedge, from both sinuses from different points a total of 3 times, and the average of these measurements was calculated. The amount of mineralization in each graft material in every radiograph was clarified by the appearance of a difference in the equivalent aluminium thickness, and the obtained results were statistically evaluated. The results showed that there were no significant differences between two graft materials statistically. These two graft materials could be good alternatives in sinus lifting procedures because of less morbidity, lower price, and good ossification. The results indicate that 2 different types of DBM achieved good ossification in the sinus lifting procedure, and there is not a considerable distinction in these 2 forms.

Maxillary Sinus Floor Elevation

The sinus lift is a procedure that is used frequently in oral surgery, different techniques exist to perform this procedure approaches, which allow the surgeon to give a sufficient bone height for planning a rehabilitative treatment with implant at the required site. In this case the unilateral lifting of the maxillary sinus floor by buccal bone window, with subsequent implant placement and lyophilized human bone in a single surgical procedure.

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.

Maxillary Sinus Floor Elevation

Maxillary sinus floor elevation using autologous or alloplastic bone grafting is often performed for implant treatment of maxillary molars; however, issues related to the donor site and complications such as infection have been reported. We performed maxillary sinus floor elevation using poly-L-lactic acid (PLLA) as a space-making material in patients with an insufficient bone mass (<3 mm) for simultaneous implantation between the alveolar crest and floor of the maxillary sinus and evaluated the newly formed bone. Conventional antrostomy of the maxillary sinus from the lateral wall was performed, and PLLA was placed on the floor of the maxillary sinus after elevating the sinus membrane. Six months after surgery, the bone mass and density were measured using quantitative computed tomography, and histological evaluation was performed. No complications were recorded. Radiological findings showed a bone-like radiopaque appearance, and histological examination revealed new bone formation in all patients. In cases with insufficient bone mass prior to simultaneous implant placement, this method of maxillary sinus augmentation allows for sufficient bone augmentation without bone grafting.

Abstract Objectives Oral surgery morbidity is highly variable based on patients’ characteristics and kind of surgical intervention. However, poor data are available in the literature regarding patient outcomes after oral surgery. The aim of this retrospective study was to evaluate patient-reported outcome and complication rates after maxillary sinus floor elevation. Materials and methods Data from the records of patients undergoing maxillary sinus elevation have been collected from a private dental office. Patient-reported outcome has been assessed using a 100-mm visual analog scale to evaluate the post-operative pain (VASpain) experienced in the first week following surgery and visual rating scales to evaluate discomfort level (VRSdiscomfort: 0 to 4) and willingness to repeat the same surgical procedure (VRSwillingness: 0 to 3). Analgesics intake, swelling onset and duration, and ecchymosis have been also recorded. Results VASpain showed moderate values in the first 2 days (< 50) post-surgery, with a tendency to progressively decrease over the next 2 days. Average assumption of painkillers was 3.93 ± 3.03. Discomfort level (VRSdiscomfort) after surgery was low (median: 1; IR: 1–0), while willingness to undergo the same surgical procedure was very high (77.63% of patients). Swelling and ecchymosis were experienced by 97.36% and 51.32% of patients, respectively, with a mean duration of 4.09 ± 1.43 and 2.21 ± 2.31 days, respectively. Membrane perforation occurred in 4 cases. Other post-operative complications were not observed. Conclusions Maxillary sinus grafting is a safe procedure, with a low complication rate and moderate morbidity that is well tolerated by patients. Particular attention is needed in case selection, surgical planning and operator expertise. Clinical relevance The analysis of patient-reported outcomes can be of great help in surgical planning and in providing correct and adequate treatment.
