“…In short, this technique makes use of the implant itself to maintain the sinus membrane in an elevated position, along with a replaced bone window creating a secluded space that allows a coagulum to spontaneously form bone to promote osseointegration of the implant. Since 2004, this technique has been thoroughly established in both clinical [15][16][17][18][19][20][21] and experimental studies. [22][23][24] However, little is known from the literature about the longterm biological response in the maxillary sinus mucosa to this technique.…”

Background Lateral sinus membrane elevation with simultaneous implant placement without grafting material (graft‐less LSFE) is a widely investigated method for bone augmentation of the maxillary sinus floor. Long‐term follow‐up studies are rare. Purpose This study aimed to investigate the long‐term effects of implants placed with graft‐less LSFE. Materials and methods The study group was comprised of 111 patients previously treated with graft‐less LSFE. The first follow‐up visit, which occurred after a mean of 5 years after surgery, included a clinical examination, cone beam computerized tomography, and panorama or intraoral radiography. The second follow‐up included panorama or intraoral radiography, and it was conducted after a mean of 8 years. Results Overall, 218 implants were placed in 127 sinuses. Nine of the 218 implants failed resulting in an overall implant survival of 95.9%. The average bone gain at the follow‐up was 4.0 ±2.0 mm. Conclusion The implant‐supported rehabilitation achieved using graft‐less LSFE was stable over time, and there was no or little impact on sinus health. Furthermore, it was concluded that the new bone formation and the amount of bone gain is proportional to the length of the implant protruding into the sinus cavity.

“… reported that 96 maxillary sinus membrane‐elevation procedures and the simultaneous placement of 239 oxidized implants, without bone grafts or bone substitutes, resulted in predictable bone formation with a high implant‐survival rate of 98.7% during a follow‐up period of 1–6 years after functional loading. Riben & Thor evaluated 83 implants placed according to 53 sinus membrane‐elevation procedures and reported a survival rate of 94.3% after a mean follow‐up time of 4.6 years. Ellegard et al.…”

Implant treatment in an atrophied edentulous posterior maxilla constitutes a challenge for the therapeutic team. The authors of the present study acknowledge that modern micro-rough surface implants in lengths of about 8-10 mm or longer and of different brands are similarly successful. Consequently, the authors propose that the use of different sinus floor elevation techniques should be considered when < 8 mm of bone is available below the maxillary sinus. The type of sinus floor elevation technique selected is mainly based on residual vertical bone height, marginal bone width, local intrasinus anatomy and the number of teeth to be replaced, although other factors (such as surgical training and surgical experience) may have an impact. It is proposed that a transcrestal sinus floor elevation approach can be considered as a first-choice method for single tooth gaps in situations with sufficient width for implant placement and a residual bone height of 5-8 mm, while lateral sinus floor elevation, with or without grafting materials, is indicated when < 5 mm of bone is available and when several teeth are to be replaced. With regard to time of implant placement, a one-stage procedure is preferred provided that high primary stability can be ensured.

Successful implant dentistry mandates implants to be placed in an appropriate three-dimensional manner that supports the prosthesis adequately. Due to the resorption patterns of edentulous jaws, the ideal position of implants required varying amounts of bone augmentation. Commonly carried out bone-augmentation procedures are Guided Bone Regeneration, onlay bone grafting and sinus floor elevation. This chapter discusses the resorption pattern of edentulous jaws, the biology of alveolar bone of relevance to the maxillofacial surgeon, the biomaterials used for augmentation and the commonly carried out augmentation procedures.
