Survival of Implants after Indirect Maxillary Sinus Elevation Procedure: A Two Years Longitudinal Study
The aim of the study was to evaluate the survival rate of two diverse implant systems with different implant surfaces with the same geometrical design. In the present study, we achieved clinical success with both kinds of implant surfaces however Bioetched implant surface showed promising results comparable to Tiunite surface of Nobel BioCare Implants. In the future, more case-controlled studies with longer follow-up are needed to validate the results of the present findings.

Sinus Floor Elevation Via the Maxillary Premolar Extraction Socket With Immediate Implant Placement: A Case Series
When immediate implant placement is considered for teeth with close proximity to the sinus floor, apical extension of the osteotomy is significantly limited, and often a staged approach is used. Implant placement into fresh extraction sockets and sinus floor manipulation using bone-added osteotome sinus floor elevation with implant placement are techniques most often used independently or sequentially. In this care report, immediate implant placement with simultaneous osteotome sinus floor elevation is an advantageous combination of two successfully used techniques. This combined approach can significantly reduce the treatment time for implant therapy in teeth with close sinus proximity and provide the operator with the ability to place implants of desired length.

Alternative Applications of Guided Surgery: Precise Outlining of the Lateral Window in Antral Sinus Bone Grafting
Computed tomography (CT) and the application of CT-based guided implant surgery allow clinicians to provide enhanced precision and accuracy in implant surgery. Because of the difficulty in transferring a patient’s often complex anatomic sinus configurations, as viewed on a preoperative CT scan, into precise osteotomy cuts at antral bone graft surgery, a prototype cutting guide was developed. The surgical guide was developed through the use of CT imaging and the stereolithographic process to precisely position the lateral window, facilitating schneiderian membrane elevation. This report demonstrates the step-by-step method to perform precise guided sinus window preparation using computer software and a stereolithographically generated surgical guide.

Indirect Sinus Lift with CPS Putty
In situations where lack of bone volume is related to an enlarged maxillary sinus, elevation of the sinus floor has been advocated for implant placement.

Schneiderian Membrane Perforation Rate During Sinus Elevation Using Piezosurgery - Clinical Results of 100 Consecutive Cases
This article presents an alternative approach that uses a piezoelectric instrument for the sinus elevation procedure.

Controlling Systematic Perioperative Anaerobic Contamination During Sinus-Lift Procedures by Using Metronidazole: An Innovative Approach
Analysis of tomodensitometric controls following sinus grafts clearly demonstrates a quite systematic lack of homogeneity. Sinus contamination by anaerobic bacteria seems almost unavoidable during bone graft surgery, and this problem may jeopardize the healing process.The aim of this study was to characterize in a systematic way the nonhomogeneities observed at 1,2,or 3 months post surgery within allogenous sinus grafts,and to assess the possible influence of a 0.5% sterile solution of metronidazole in corporated in the sinus bonegraft.

Sinus Augmentation for Single-Tooth Replacement in the Posterior Maxilla: A 3-Year Follow-up Clinical Report
A technique for single-tooth sinus lift and simultaneous implant placement in the posterior maxilla is presented. Ten hydroxyapatite-coated cylindric implants, 13 to 15 mm in length, were placed together with a composite bone graft of demineralized freeze-dried bone allograft and autogenous bone in 10 adults. Surgical technique and anatomic considerations are discussed. Follow-up of 3 years showed successful function and no cervical bone loss in all patients.

Radiological Findings of the Post-Sinus Lift Maxillary Sinus: A Computerized Tomography Follow-Up
The purpose of this article is to present radiological findings of a short-term (8 to 10 months) computerized tomography (CT) follow-up study on 1-stage maxillary sinus lift cases.

Predictability of Simultaneous Implant Placement in the Severely Atrophic Posterior Maxilla: A 9-Year Longitudinal Experience Study of 2,132 Implants Placed into 731 Human Sinus Grafts
Simultaneous implant placement into sinus floor grafts can be a predictable treatment option for patients with at least 1 to 2 mm of vertical residual bone height when careful case planning and meticulous surgical techniques are used.

Sinus Floor Augmentation With Simultaneous Implant Placement Using Choukroun’s Platelet-Rich Fibrin as the Sole Grafting Material: A Radiologic and Histologic Study at 6 Months
Sinus augmentation with simultaneous implant placement without bone graft material is a hotly debated technique. This technique could be improved and secured by the use of an autologous leukocyte-and platelet-rich fibrin (PRF) (Choukroun’s technique) concentrate. The objectives of this study were to assess the relevance of PRF clots and membranes as the sole filling material during a lateral sinus lift with immediate implantation using radiologic and histologic analyses in a case series.

Healing in Smokers Versus Nonsmokers: Survival Rates for Sinus Floor Augmentation with Simultaneous Implant Placement
Evidence suggests that smoking is detrimental to the survival of dental implants placed in grafted maxillary sinuses. Studies have shown that improving bone quantity and quality, using rough- surfaced implants, and practicing good oral hygiene may improve outcomes. In this prospective study, the long-term survival rates of implants placed simultaneously with sinus grafting in smokers and non- smokers were compared.

The Effect of Piezoelectric Use on Open Sinus Lift Perforation: A Retrospective Evaluation of 56 Consecutively Treated Cases From Private Practices
The lateral window approach to maxillary sinus augmentation is a well-accepted treatment option in implant dentistry. The most frequent complication reported with traditional techniques has been the perforation of the Schneiderian membrane, with erforation rates ranging from 11% to 56%. The purpose of this retrospective, consecutive case series from two private practices was to report on the rate of Schneiderian membrane perforations and arterial lacerations when a piezoelectric surgical unit was used in conjunction with hand instrumentation to perform lateral window sinus elevations.

DENTAL IMPLANT PLACEMENT ASSOCIATED augmentation of the sinus floor in the severely atrophic maxilla can be performed in 1- or 2 surgical stages depending on the height of the residual alveolar bone.

Maxillary Sinus Membrane Repair: Update on Technique for Large and Complete Perforations
Maxillary sinus membrane perforation is the most common complication that occurs with sinus elevation augmentation surgery. A technique using a slow resorbing type I collagen membrane for repair of large and complete sinus membrane perforations is described. The biocompatibility and semirigid structural integrity of this membrane, along with external tack fixation, allows for optimal membrane stabilization and maintenance. (Implant Dent 2008;17:24–31)
