Normal healing procedure of bone involves various sequential events to develop bone and bridge the bone -to- bone gap. When this healing occurs with a metal (titanium) fixture on one side, it is called as osseointegration. After extensive studies on this topic, it is found that this procedure occurs in presence of various biologic constituents that are spontaneously released at the site. Thus, to accelerate normal healing after implant placement and make results more predictable, it has been proposed to use these autologous factors in the osteotomy site. Since it is the beginning of a new revolution in dental implantology, right now it is essential to analyze all possible combinations of host conditions, bone quality and quantity and bio factors being used. This can definitely be a boon for the patients with compromised systemic or local conditions.

Background: This technique video reviews anatomic total shoulder arthroplasty (TSA) with a stemless humeral component using a representative case example. Indications: Stemless TSA is indicated for patients with symptomatic glenohumeral arthritis typically younger than 65 years of age. Stemless TSA may be used for other glenohumeral degenerative conditions such as avascular necrosis or posttraumatic arthropathy, provided acceptable humeral bone quality is confirmed intraoperatively using a thumb-press test. Poor bone quality is the primary contraindication. Technique Description: Preoperatively, computed tomography is typically used for planning, and intraoperative navigation through magnetic resonance imaging is also useful. The procedure’s critical elements include beach chair positioning, standard deltopectoral approach with lesser tuberosity osteotomy (LTO), freehand proximal humeral osteotomy, perpendicular proximal humeral exposure and subsequent preparation over a central guidewire, stemless implant and humeral head sizing, perpendicular glenoid exposure and implant placement, and final humeral implantation with LTO repair/fixation. A phased rehabilitation protocol includes 6-week sling immobilization to protect the subscapularis/LTO repair and return to normal activities between 3 and 6 months postoperatively. Discussion/Conclusion: Stemless TSA shows promising early and mid-term outcomes with complication rates, including humeral loosening rates, similar to standard stemmed components. Potential complications include neurovascular injury, infection, glenoid or humeral component loosening, and rotator cuff failure.

Despite numerous advantages over multislice computed tomography (MSCT), including a lower radiation dose to the patient, shorter acquisition times, affordable cost, and sometimes greater detail with isotropic voxels used in reconstruction, allowing precise measurements, cone beam computed tomography (CBCT) is still controversial regarding bone quality evaluation. This paper presents a brief review of the literature on accuracy and reliability of bone quality assessment with CBCT and a case report with step-by-step predictable treatment planning in esthetic zone, based on CBCT scans which enabled the clinician to evaluate, depending on bone volume and quality, whether immediate restoration with CAD-CAM manufactured temporary crown and flapless surgery may be a treatment option.

Proof Of Principle

Dental implants are widely accepted as the golden standard for the rehabilitation of an edentulous site following the extraction of a tooth. The ideal time for implant placement is dependent on the time required for partial or complete tissue healing and the adequacy of socket dimensions. The use of autologous growth factors is a promising new concept that aids clinicians in minimizing treatment time and increasing patient satisfaction. The purpose of this paper is to introduce a protocol for “accelerated-early” implant placement. In this protocol, platelet rich fibrin is employed to accelerate soft and hard tissue healing and to provide a better-healed recipient site for accelerated, early implant placement. Histological analysis revealed that at 6 weeks postextraction, the application of our approach resulted in delicate newly formed bone showing intense osteoblastic activity surrounded by connective tissue as well as areas of mineralized tissue. The present study is a proof-of-principle study of the acceleration of the physiologic postextraction healing sequelae with the use of autologous growth factors. The accelerated-early implant placement concept is a bioengineered protocol that may aid clinicians to achieve increased primary stability, by placing implants in ridges in an advanced stage of bone healing, while offering patients the benefits associated with early implant placement. Controlled studies are warranted to verify the reproducibility of this treatment concept and identify specific indications where the use of the presented technique can lead to significant clinical results.

Objective: Implants placed in the posterior region of the maxilla have a high incidence of implant failure due to poor bone quality, especially when immediate implant loading is needed. Immediate Progressive Loading (IPL) can enhance bone quality and may offer an alternative solution when Immediate Implant loading is needed. Methods: Six patients (one male and five females; 34-62 years old) were included in this study. Twelve implants were inserted in the posterior region of the maxilla. Resonance Frequency Analysis (RFA) was performed at the time of implant placement and after 1, 2, 3 and 6 months. ISQ (Implant Stability Quotient) values were compared between the Delayed Loading (DL) group after 2 months and the Progressive Loading (PL) group and between different time points for each group. Results: At implant placement, the mean ISQ values for PL and DL implants were 63 and 57, respectively. One month after implant placement, the mean ISQ value for PL implants was 73. Two months after implant placement, the mean ISQ value for PL implants was 75. Three months after implant placement, the mean ISQ values for PL and DL implants were 76 and 69, respectively. Six months after implant placement, the mean ISQ values for PL and DL implants were 79 and 76, respectively. Conclusion: Despite its limitations, this pilot study indicated that compared to DL, PL can enhance bone density and implant stability, resulting in greater early functionality and fewer surgery sessions.

Achieving an excellent aesthetic outcome in postextraction dental implant placement in the anterior maxilla is a challenging procedure for clinicians. In fact, there is an increased risk for soft tissue recession at the facial aspect which may require supplementary connective tissue grafts to accomplish the final aesthetic result. The aim of this case report is to describe a regenerative technique using autologous plasma rich in growth factors fibrin plug for preservation of soft tissue architecture around an implant immediately placed into an extraction site in the anterior maxilla. Such a procedure allowed for guided bone regeneration without the need for vertical releasing incisions and primary healing, thus showing a pleasant gingival contour at the facial aspect after a single stage surgery. Integrating this technique into common practice could provide important benefits for the patients regarding aesthetics, without any risk of infection or transmission of diseases.

This study analyzed the examination records and radiographs of 247 patients (144 male, 103 female) who received an OSSTEM Implant (Seoul, Republic of Korea) at the dental clinic at Chosun University, Korea, between January 2002 and December 2005. The overall success rate in patients who received an OSSTEM Implant from surgeons of the Department of Oral Surgery at our hospital was 93.1%, making the overall failure rate relatively low (6.9%). The failure rate for the maxillary molar tooth was slightly higher, at 9.95%, probably as a result of its relatively lower bone quality and reduced osteoid volume caused by pneumatization of the maxillary sinus. Thus, to determine appropriate treatment, it is necessary to accurately determine bone quality and volume. This can be achieved with implant placement analysis of computed tomography, precise preoperative planning, and sufficient technical experience.
