AIMS: The primary objective of this study was to compare the in vivo performance, namely in terms of quantity of newly formed bone and bone-to-material contact (osteoconductivity), of three hydroxyapatite-based biomaterials (HA) of different origins (natural or synthetic) or manufacturing process in a sinus lift model in rabbits. The secondary objective was to correlate the findings with the physical and topographical characteristics of the biomaterials. MATERIALS AND METHODS: Two bovine HA manufactured with different processes (bovine hydroxyapatites [BHA] and cuttlebone hydroxyapatite [CBHA]) and a synthetic hydroxyapatite (SHA) sintered at high temperature were characterised with scanning electronic microscopy (SEM) and the measurement of specific surface area (BET)...

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...

PURPOSE: To report the outcome of graftless osteotome sinus floor elevation (OSFE) in order to evaluate whether apical bone gain depends on the initial residual bone height and whether the initial residual bone height has an influence on the amount of marginal bone loss. Furthermore the study aimed to assess if perforations of the Schneiderian membrane or residual bone height are potential predictors of implant survival. MATERIALS AND METHODS: In this retrospective study all patients were included who were treated between 2001 and 2010 and received dental implants in combination with OSFE in a private practice...

Perforation of the Schneiderian membrane is a common complication of sinus augmentation. The aim of this retrospective study was to assess the associations between the lateral wall technique and the ridge approach and the risk of perforation, together with the relations between the thickness of the membrane and the risk of perforation. We studied 200 patients (103 men and 97 women) who had cone-beam computed tomography (CT) before a sinus lift with either a lateral wall technique (n=100) or the rigid approach (n=100) for insertion of prosthetic implants...

Osteoid osteoma, a rare benign osteoblastic tumor first described by Jaffe in 1935, is characterized as a small but painful lesion that mostly affects younger people. Usually benign and harmless, osteomas are removed for pain or esthetic reasons.Piezoelectric surgery is also increasingly being used effectively in major and minor osseous oral and maxillofacial surgeries, in delicate areas. It is used regularly for various procedures, including sinus lift procedures, bone graft harvesting, osteogenic distraction, ridge expansion, inferior alveolar nerve decompression and lateralization, cyst removal, dental extraction, and impacted tooth removal...

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...

Some graft materials such as a heterologous porcine cortical lamina have an excellent capacity in creating recipient sites that can be filled with cortico-spongious collagenated bone paste that reabsorbs, allowing for the reformation of good-quality bone. In this work a technique is proposed which makes use of resorbable cortical lamina in order to create a new sinus floor that can be filled with cortico-spongious bone paste. The adequate vascularisation of the graft combined with the integration of the lamina, which does not need to be removed, makes it possible to propose this technique as a potential alternative to those used so far...

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...

This report demonstrates the clinical use of a modified, truly anatomic, root analogue zirconia implant for immediate replacement of a right mandibular first premolar. A 22-year-old female patient with chronic apical periodontitis of the right mandibular first premolar was referred and the tooth was carefully extracted. A truly anatomical, root identical, roughened zirconia implant modified by macro-retentions was manufactured and placed into the extraction socket by tapping 3 days later. After 4 months a composite crown was cemented in place...
