Different Techniques For Sinus Floor Elevation: A Review Part II – Indirect 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.

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.

The aims of this study were to propose a minimally invasive lateral approach technique for maxillary sinus floor elevation (MSFE) with simultaneous implant placement and to evaluate the surgical outcome and complications of this technique. This study reviewed 49 surgeries of MSFE with simultaneous implant placement (n = 83) using a minimally invasive lateral approach. A circular shape window with a diameter of 5 to 6 mm and an area of 20–30 mm2 was made on the lateral wall of the maxillary sinus. After elevation of the Schneiderian membrane, the xenograft was used for bone grafting. The MSFE was possible with a minimum-sized window in 47 of 49 cases. For the remaining 2 cases, MSFE with a minimum-sized window was failed. In one case, it was expanded to be more than 30 mm2 to repair the membrane perforation. In another case, MSFE was performed by forming two minimum-sized windows. Post-operative bleeding after MSFE occurred in one anticoagulant-treated patient. There was no failed implant during the follow-up period (mean 22 months). A minimally invasive lateral approach through a small circular window with a diameter of 5 to 6 mm is a feasible and safe technique for MSFE with simultaneous implant placement.

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 Displacement

An increasing number of studies have investigated the use of osteotome sinus floor elevation (OSFE) with simultaneous implant placement for maxillary sinus floor residual bone height (RBH) <4 mm. Many studies have reported good clinical results, but very few have reported complications related to this procedure. Here, the case of a 50-year-old female patient with an RBH in the left upper posterior region of 1–4 mm, who underwent OSFE with simultaneous placement of three Bicon short® implants, is described. One of the implants was found to be displaced during the second-stage surgery. The displaced implant was removed using piezosurgery, OSFE with simultaneous implant placement was repeated, and the missing tooth was reconstructed 6 months later. This case suggests that OSFE with simultaneous implant placement is feasible for severely atrophic maxillary sinus floor, but carries a risk of implant displacement.

Maxillary Sinus Floor Elevation

Abstract Background: The present study examined the effectiveness of high-purity macro/microporous beta-tricalcium phosphate (HPMM β-TCP) as a bone grafting material for maxillary sinus floor elevation by morphometric and histopathological, histomorphometric evaluations.Methods: Ten maxillary sinus ﬂoor elevation procedures using 100% HPMM β-TCP were performed on 10 patients. Morphometric evaluation was carried out by CT imaging immediately after augmentation and prior to dental implant placement after 7 months.Histopathological and histomorphometric evaluation were carried out by bone biopsy retrieval at the time of dental implant placement 7 months after sinus floor elevation. Results: All 10 sinus floor elevations were successful. Morphometric evaluation by CT images showed that the vertical height and the volume gained by sinus floor elevation decreased 7 months after surgery. Histopathological evaluation by bone biopsy retrieval specimens showed no signs of inﬂammation at the newly formed bone area and the native alveolar bone area. New bone formation was observed at the cranial side from the native alveolar bone. The newly formed bone had a trabecular structure and was in intimate contact with the HPMM β-TCP material. Histomorphometric evaluation by bone biopsy retrieval specimens revealed an average new bone volume of 33.97%±2.79% and an average residual HPMM β-TCP volume of 15.81%±4.52%.Conclusions: In this study, HPMM β-TCP showed the osteoconductive properties for vertical augmentation of the atrophied maxilla by means of a maxillary sinus ﬂoor elevation procedure allowing subsequent dental implant placement after a 7-month healing period.

The Mean

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.
