Abstract Sinus lift surgery has become more common as patients choose dental implants for tooth replacement. The recent development of a graft material that stimulates osteogenesis coupled with the application of tissue engineering principles has allowed for refinement of this surgical modality. A simple nontraumatic subantral sinus lift microsurgery is presented. This sinus lift microsurgery resulted in a 97% implant success rate.

Sinus lift operations have become a prerequisite for implantologists in the rehabilitation of atrophic posterior maxilla. Alloplasts and xenografts are the recent innovation in the world of grafting materials and have evolved in such a way as to compensate the need for autografts to be used in conjunction. In order to perfect the grafting materials, histomorphometry is the most often tool used to study the success of the augmentation. This article has tried to commemorate the importance of histomorphometry in maxillary antroplasty and also the success rate of β-tricalciumphosphate and deproteinized bovine bone as an augmentation material in maxillary augmentation.

Dental implants really have transformed the reconstruction and strategic planning of fixed prosthodontics in the edentulous posterior maxilla. Increased bone volume via elevation of sinus membrane enables dental implants to be positioned in dysplastic maxillary ridges. The purpose of the research was to determine retrospectively the volume of hard tissue height acquired through a transcrestal method to sinus lifting utilizing osteotomes, together with the concurrent positioning of implants. Documents from the previous 2-year span of partially edentulous cases checked at Saveetha Dental Hospital were searched for patients undergoing implantation to substitute teeth missing in a posterior edentulous maxillary area with inadequate vertical osseous height. The inclusion criterion, sinus lift operation, was performed without bone grafts. A maximum of 42 people was selected. Among these patients, 35 were classified as cases recommended for indirect sinus lift while 45 were given implants. The implants being used are 3.5 mm or 4.5 mm diameter and 10.5, 11 or 13 mm length. The average survival rate for implants was 97.78 per cent. The mean bone height estimated from alveolar crest to the base of the implant just at the time of implantation was 6.79 mm ± 1.35 mm. Measured mean bone height at the six-month follow-up period was 11.4 mm ±0.88 mm, which was significant (p < 0.05). Transcrestal osteotomy with implants tenting sinus membrane without extra graft material might show a substantial mean osseous height increase of 4.6 mm.

Detailed information about graft material characteristic is crucial to evaluate their clinical outcomes. The present study evaluates the physicochemical characteristics of two xenografts manufactured on an industrial scale deproteinized at different temperatures (non-sintered and sintered) in accordance with a protocol previously used in sinus lift procedures. It compares how the physico-chemical properties influence the material performance in vivo with a histomorphometric study in retrieved bone biopsies following maxillary sinus augmentation, in 10 clinical cases. X-ray diffraction analysis revealed typical structure of hydroxyapatite for both materials. Both xenografts are porous and exhibit intraparticle pores. Strong differences were observed in terms of porosity, cristallinity, and calcium/phosphate. Histomorphometric measurements on the bone biopsies showed statistically significant differences. The physicochemical assessment of both xenografts in accordance with the protocol developed at industrial scale confirmed that these products present excelent biocompatibilitity, with characteristics similar to natural bone. The sintered HAs xenograft exhibit higher osteoconductivity although were not complete resorbable (30.80&plusmn;0.88% residual material). On the other hand, the non-sintered HAs xerograft induced about 25.92&plusmn;1.61% of new bone and almost complete degradation after 6 months implantation. Differences in physico-chemical characteristics found between the two HAs xenograft determine different behavior of this material.

Objectives:Mineralized plasmatic matrix is reported to improve the quality of the bone/fibrin mixture, creating a stable and easy to handle homogeneous material. However, few studies evaluate the use of the mineralized plasmatic matrix during sinus lift with the simultaneous placement of dental implants. Purpose: This study evaluated the efficiency or not of MPM compared to the xenograft bone grafting in the maxillary sinus lift. Patients and methods:This study was conducted randomly on patients selected for treatment with a total of sixteen lateral windows sinus lift with simultaneous implant placement. Their ages ranged between 20 and 60 years old. Participating patients were divided into two groups equally and randomly The control group: eightsinus floor elevation was performed using simultaneous implant placement. As a grafting material, Xenograft was used. The study group: eight Sinus floor elevation was achieved with simultaneous implant placement. Xenograft has been used in the form of MPM as a grafting material. CBCT taken before and after sinus augmentation to measure bone volume and height after 1 week of baseline (T0), after 6 months (T1), and after 12 months of baseline (T0) (T2). The Osstell(PT) was used for assessment implant stability at implant insertion (PT0) as well as for loading visit (PT1). Result:A significant difference was observed between the two groups in bone volume (p=0.049). No significant difference was observed between the two groups (p=0.129) in height of graft. Conclusion:MPM eliminated the need for barrier membranes when a guided bone regeneration procedure is considered.The useofMPM as a grafting bone offered greater graft stability and handling.

Osseointegration can be defined as a direct connection, both structural and functional, between living bone and the surface of an artificial implant. Indeed, the word comes from the Greek term for 'bone' and 'to make whole'. In dentistry, once dental implants are placed, the body will react with osseointegration, enabling the implants to become a permanent part of the jaw. There are many benefits to this type of implant, compared with traditional tooth replacement options, not least that dental implants mimic the strength and functionality of a natural tooth. Dr Shuhei Tsuchiya is a researcher based in the Division of Oral and Maxillofacial Surgery at Nagoya University, Japan, who is interested in a range of areas, including regenerative medicine and the extracellular matrix. One of his key preoccupations, though, is shedding light on osseointegration. He and his team are working to unravel the mysteries of the mechanism.
