INTRODUCTION: The term oro-antral fistula is understood to mean of fistular canal covered with epithelia which may or may not be filled with granulation tissue or polyposis of the sinus mucous membrane. With the presence of a fistula the sinus is permanently open, which enables the passage of microbial flora of the oral cavity into the maxillary sinus and the occurrence of inflammation with all possible consequences. Every now and then various researchers have proposed innumerable techniques to treat this defect...

BACKGROUND: Sinus lift is a bone augmentation procedure that improves the alveolar crest height in an atrophic posterior maxilla. However, the regenerated bone volume can vary and generally has a tendency to decrease after sinus operation. This article describes nongrafted maxillary sinus lift using a bioresorbable unsintered hydroxyapatite combined with poly L-lactide (HA/PLLA) mesh plate device and dental implant placement in an atrophic posterior maxilla, after which continuous bone gain was observed around the implant apex during a postoperative follow-up period of 3 years...

Implants have a predictable outcome and are the foremost treatment modality for prosthetic rehabilitation of edentulous patients. Due to loss of bone after extraction and pneumatization of maxillary sinus, there is insufficient bone volume for implant placement. The direct maxillary sinus lift procedure has been performed with different grafting materials (autogenous bone grafts, alloplasts, allografts, and xenografts) and without grafting material, having new bone formation around the implant. There is no evidence to prove the need for grafting material in all direct sinus lift procedures, hence the need for this review...

OBJECTIVE: In this study, we compared the success of sinus lifting and alternative treatment methods in applying dental implants in cases lacking adequate bone due to pneumatization of the maxillary sinus. METHODS: In a computer environment, 3D models were created using computerized tomography data from a patient. Additionally, implants and abutments were scanned at the macroscopic level, and the resulting images were transferred to the 3D models. Five different models were examined: a control model, lateral sinus lifting (LSL), short dental implant placement (SIP), tilted implant placement (TIP) and distal prosthetic cantilever (DC) use...

In the present paper the use of tapered-screw bone expanders (TSBEs) is proposed, in combination with the placement of tilted implants in close proximity to the anterior sinus wall, solving the problem of the reduced height of the alveolar bone in the sub-antral area. The Authors named the procedure: Tilted Implant Expansion Osteotomy (TIEO). Fifteen patients (10 females and 5 males, mean age 47.8±8.15 years) with distal edentulous maxillae were enrolled in this study. For each edentulous site 2 implants were placed, the anterior implant in the area of the most anterior missing tooth while, the posterior implant, immediately in front of the maxillary sinus, with an inclined position...

The clinician contemplating reconstruction of the posterior maxilla with osteointegrated implants must overcome a number of anatomic challenges. Buccolingual and/or apico-occlusal atrophy of the edentulous ridge and pneumatization of the maxillary sinus often limit the volume of bone available for implant placement. Many clinicians advocate augmentation of the maxillary sinus to increase the dimension of available bone for implant placement. A female patient aged 38-year old was undergone maxillary sinus augmentation (sinus lifting) after improper implant placing in upper right molar area...

After a sinus lifting procedure, the compartment around the implants under the sinus mucosal lining in the sinus floor is filled with a blood clot from surrounding bleeding. The aim of this study was to evaluate the feasibility of bone formation following graftless sinus lifting with the simultaneous placement of dental implants. Thirty graftless sinus lifting procedures were performed and 72 dental implants placed in 18 consecutive patients, using the lateral window approach. Clinical and radiological follow-up was conducted throughout the 6-month healing period...

The aim of this paper is to introduce an alternative technique for the treatment of oroantral communication (OAC). Closure of OAC, reconstruction of the posterior maxilla by sinus-lifting procedure with a particulate xenograft, and implant insertion were performed in the same operation. A lateral antral approach was used in the sinus elevations. The sinus membranes were elevated gently around the perforation area, and then a barrier membrane was used to close the perforation. Care was taken not to extend the perforation...

BACKGROUND: The sinus lift was first described in 1974 and it has proven to be a predictable procedure ever since. The complications of this surgical procedure are reported in the literature to be low, and can include acute maxillary sinusitis, scattering of the grafting material into the sinus cavity, wound dehiscence and Schneiderian membrane perforations. We aimed to evaluate the rate of acute maxillary sinusitis after sinus lift procedures and the appropriate management strategies...

OBJECTIVES: Cone-beam computed tomography (CBCT) has been used in the literature to evaluate Schneiderian membrane thickness (SMT), but its accuracy has never been validated. The primary aim of this study was to compare the SMT measured by CBCT to the gold standard histological assessment. The correlations between SMT and anatomical structures of the maxillary sinus and alveolar bone were also tested. MATERIALS AND METHODS: Fourteen fresh cadaver heads were used for the study, and 28 sinus lift augmentation procedures were performed to obtain the membrane samples...

BACKGROUND: The aim of this study was to present a case series treated with an atraumatic procedure for maxillary sinus lift by crestal approach. This technique avoids the use of classical osteotomes, thus decreasing complications due to percussive and vibratory forces. METHODS: Three cases of partial edentulism in the distal maxillae with inadequate bone volume are treated by using SinCrest procedure (Meta, Reggio Emilia, Italy). With the guide of surgical templates, the sinus lift was performed, and implants were placed during the same procedure...

BACKGROUND: It is important to visualize the phenomenon which occurs in actual clinical cases to decide the timing of implant placement subsequently after sinus graft. Although several clinical cases of bone augmentation using xenograft have been evaluated, the number of those reports which have described bone remodeling by alloplasty are not sufficient. FINDINGS: In the present report, to investigate bone remodeling histologically after maxillary sinus augmentation with porous hydroxyapatite alloplast, bone cores from the sinus floor of three female nonsmoking patients (aged 64-73 years) were collected 6 months after sinus lift surgery, embedded in methyl methacrylate resin, and prepared by conventional methods...
