This study sought to evaluate the effect of the type of grafts used in sinus lifting. A review of literature through MEDLINE search covering the period 1980 ~ 2006 was performed. After screening, this study was narrowed down to 2,452 patients receiving sinus lift grafts wherein 7,151 implants were placed. In this study, the types of grafts used in sinus augmentation were autogenous bone, allogenic bone, corticocancellous block bone, and various alloplastic materials. The success rate varied from 69% to 100% depending on the graft material type. The highest success rate was reported for the autogenous bone, with high success rates recorded for the most part in most studies.

There have been reports of successful bone formation with sinus floor elevation by simply elevating the maxillary sinus membrane and filling the sinus cavity below the lifted sinus membrane with a blood clot. But, in a review of the current literature, we found no animal study that substantiated blood clot's ability in this respect. The aim of this study was to investigate the effect of the method of maxillary sinus floor augmentation using the patient's own venous blood in conjunction with a sinus membrane elevation procedure. An implant was placed bilaterally in the maxillary sinus of six adult mongrel dogs so that it protruded 8 mm into the maxillary sinus after sinus membrane elevation. On one side of the maxillary sinus, the resultant space between the membrane and the sinus floor was filled with autologous venous blood retrieved from the dog. On the opposite side, the maxillary sinus was left untreated as a control. The implants were left in place for six months. The mean height of the newly formed bone in the sinus was 3.7 mm on the side without venous blood and 3.5 mm on the side with venous blood (p>0.05). There was no difference between the two sides regarding new bone height in the sinus. Our results indicate that filling the space between the lifted sinus membrane and the sinus floor with venous blood has no effect on bone formation around implants placed in the maxillary sinus cavity.

Methods for restoring the posterior portion of the maxilla with delayed and simultaneous sinus lift, composite graft and placement of TPS cylinder and screw type implants are presented. Sinus grafting is needed because of minimal remaining alveolar bone and supporting posterior maxillary portion, The composite graft material uses a combination of autogeneous bone from tuberosity, dimeneralized freeze dried allogenic bone and hydroxylapatite with saline. Since 1991, feb, 1 sinus graft with delayed implantation of 3 cylinder implants and 5 sinus grafts with simultaneous placement of 4HA coated screw typed, 8 TPS cylinder typed implants have been performed for 6 patients. None of the 15 restored implants have been lost, Temporization of prosthesis was done about 2-5 months before final prosthetic work, None of them shows any severe complication.

Sinusitis has been reported as a complication of sinus lift surgery. Obstruction of the sinus outflow tract by mucosal edema and particulate graft material may result in sinusitis. Two main surgical procedures have been proposed for the treatment of associated infectious complications; inferior meatal antrostomy and functional endoscopic sinus surgery through transnasal approach. We performed superior lateral wall antrostomy through introral approach in patient suffering from the sinusitis after sinus floor augmentation and implant installation. This procedure permitted easier access to the maxillary sinus for treat sinusitis caused by sinus lifting.

Purpose: The purpose of this study was comparison of survival rate of implant as two sinus elevation techniques and when window opening procedure had done it was comparison of survival rate of implant between the procedure of implantation after 6 month of sinus elevation to allow healing period and that of implantation with sinus elevation simultaneously. Material and Methods: All 79 of patients treated at DanKook University Dental Hospital Dept. of Periodontics for 164 implantation of maxillary posterior edentulous area with sinus elevation. Sinus elevation technique was divided of the technique : Osteotome technique and window opening technique. Result: 14 implants among 96 implants was failed implants of using osteotome for sinus elevation whereas one implant of 68 implants was failed of using window opening technique. Conclusion: Window opening technique had higher survival rate than osteotome technique. In case of window opening, there was no significant difference of immediate implantation and delayed implantation.

Sinus floor elevation is a predictable and standard procedure for the treatment of the posterior maxilla before insertion of dental implants. Although overall complication rates are low, complications can occur including sinus membrane perforation, infection of sinus, swelling and hemorrhage. The most common complication is membrane perforation. Recently, various techniques and materials for repair of perforation to the sinus membrane have been proposed. The purpose of this article is to report on various techniques and materials that can be used for repair of perforations to the sinus membrane. The search protocol used was the following electronic database: Pubmed, with a time limit from 1998 to 2009. The key words such as 'sinus lift', 'sinus augmentation', 'sinus floor elevation', 'sinus graft', 'sinus perforation', 'repair of sinus perforation' and 'repair of sinus membrane' were used, alone and in combination, when searching the database. Various techniques have been proposed to manage of perforation of sinus membranes. These include that the use of collagen membranes, demineralized freeze-dried human lamellar bone sheets, processed human allografts, lamella bone, buccal fat pads and suturing. Implant success rate ranges from 69.9% to 98.9%.

Background: The presence of septa increases the risk of Schneiderian membrane perforation during sinus lift procedure, and therefore, the chance of graft failure increases. We present a safe method of managing septa and, in particular, overcoming small and palatally located septa. Methods: After the elevation of the flap and the creation of a small bony window positioned anterior to the septum, the Schneiderian membrane is lifted carefully. A thin and narrow osteotome is then placed at the indentation created at the base of the septum, and mobilization of the septum is achieved by gentle malleting. The membrane is again carefully lifted up behind the septum. Results: There was one small membrane perforation case in all 16 cases, and none of these patients showed postoperative complications such as implant failure, infection, or maxillary sinusitis. Conclusions: This technique is useful for overcoming the problem of maxillary sinus septa hindering the sinus floor elevation procedure, leading to fewer complications.

Objectives: The purpose of this animal research was to compare bone regeneration in augmented rabbit maxillary sinuses treated with demineralized particulate human-tooth graft and anorganic bovine bone by immunohistochemical analysis. Materials and Methods: Piezoelectric bilateral sinus augmentation was performed in eight adult rabbits. In the control group, anorganic bovine was grafted in the maxillary sinus following elevation of the sinus membrane. In the experimental group, demineralized human particulate tooth bone was grafted in the sinus. Bone regeneration in augmented sinuses was evaluated by immunohistochemical analysis using various markers of osteoprogenitor cells. Results: The number of bromodeoxyuridine-labeled cells was significantly higher in the experimental group than in the control group at eight weeks. The immunoreactivity of proliferating-cell nuclear antigen was increased slightly in the experimental group relative to the control group at eight weeks. Other bone markers were expressed equally in the two groups. Conclusion: In the rabbit maxillary sinus, higher osteoinduction was correlated with demineralized human particulate tooth bone grafting than with anorganic bovine grafting.
