OBJECTIVE: To test the hypotheses of no differences in implant treatment outcome after maxillary sinus floor augmentation (MSFA) with synthetic bone substitutes (SBS) compared with other grafting materials applying the lateral window technique. MATERIALS AND METHODS: A MEDLINE/PubMed, Embase and Cochrane Library search in combination with hand-search of selected journals was conducted. RESULTS: Five randomized controlled trials with low risk of bias fulfilled the inclusion criteria...

The potential application of stem cell biology in human dentistry is a new and emerging field of research. The objective of the current review was to study the efficiency of mesenchymal stem cells (MSCs) in sinus lift augmentation (SLA). A literature review was performed in PubMed Central using MeSH keywords such as sinus lift, MSCs, dental implants, and augmentation. The searches involved full-text papers written in English, published in the past 10 years (2007-2017). The review included in vitro and in vivo studies on the use of MSCs in SLA...

The aim of this review was to test the hypothesis of no difference in the efficacy of bone regeneration when using stem cells in maxillary sinus floor augmentation surgery in comparison to other grafts. Nine randomized clinical trials and one follow-up study involving human subjects were identified through a search of the PubMed/MEDLINE, Scopus, Cochrane, and Web of Science databases, supplemented by a hand search. No significant difference between groups was found for the implant survival rate, increase in bone height, marginal bone loss following implant placement, or new bone formation...

BACKGROUND: Recombinant human bone morphogenetic protein-2 in an absorbable collagen sponge carrier (rhBMP-2/ACS) has been shown to support significant bone formation when used to augment the maxillary sinus for implant dentistry. Nevertheless, bone biomaterials have been suggested to extend rhBMP-2/ACS with limited support of the merits of such approaches. OBJECTIVES: To evaluate local bone formation/dental implant osseointegration following implantation of rhBMP-2/ACS combined with a ceramic bone biomaterial using a mini-pig sinus augmentation model...

OBJECTIVE: The combination of calcium phosphate with blood-derived growth factors (BDGF) has been widely used in bone regeneration procedures although its benefits are still unclear. The purpose of this study was to evaluate whether or not BDGF improves the efficacy of a modified carbonated calcium phosphate biomaterial in sinus floor augmentation. MATERIAL AND METHODS: Ten patients underwent 20 sinus floor augmentation procedures using nanostructured carbonated hydroxyapatite (cHA) microspheres alone or associated with BDGF in a randomized controlled clinical trial...

Recent human genetic studies have shown that Gβ5 is related to various clinical symptoms, such as sinus bradycardia, cognitive disability, and attention deficit hyperactivity disorder. Although the calcium signaling cascade is closely associated with a heterotrimeric G-protein, the function of Gβ5 in calcium signaling and its relevance to clinical symptoms remain unknown. In this study, we investigated the in vitro changes of store-operated calcium entry (SOCE) with exogenous expression of Gβ5. The cells expressing Gβ5 had enhanced SOCE after depletion of calcium ion inside the endoplasmic reticulum...

RATIONALE: In this case study, a modified transcrestal approach was applied to the patient of extremely atrophic posterior maxilla. We analysis the Implant Stability Quotient values (ISQ) to monitor implant stability, and the cone-beam computer tomography (CBCT) to evaluate the bone regeneration. PATIENT CONCERN: A 26-year-old female patient visited our hospital with no contraindications for dental implants and a loss of the maxillary right first molar. DIAGNOSE: Examination by CBCT demonstrated the posterior maxilla was extremely atrophic, the residual bone height (RBH) of #16 was 3...

Introduction: Little is known regarding the success, failure, or complication rates of advanced implant procedures in patients after discontinuation therapy of long-term medications for the treatment of chronic myelogenous leukemia (CML). This case report presents initial results of a case involving implant placement in the mandible and maxilla as well as reduction of palatal oral pigmentation in a patient discontinuing long-term tyrosine kinase inhibitor (TKI) therapy for CML. Case Presentation: A 57-year-old male was referred to the Department of Periodontics, University of Washington, Seattle, Washington, for an assessment of edentulous areas (tooth sites #3 and #14) and failing tooth #19...

Increased resting heart rate (HR) contributes to higher cardiovascular mortality and morbidity in the healthy as well as in people with cardiovascular diseases, possibly due to elevated blood pressure (BP) among other mechanisms. Data on the relationship between HR and central (aortic) BP remains controversial, however, and concerning β-blockers, it has been proposed that pharmacological HR lowering is associated with augmentation of central BP. We aimed to study the role of pharmacologically unaffected HR on central BP indices in sick sinus syndrome patients with a permanent cardiac pacemaker in the HR range from 40 to 90 bpm...

PURPOSE: In the presence of severe sinus mucosal thickening, the ostium can be blocked when the sinus membrane is lifted, causing drainage disturbances and sinusitis. Here, we present 3 cases in which maxillary sinus floor elevation was performed using a crestal approach in the presence of severe sinus mucosal thickening (>10 mm). MATERIALS AND METHODS: The effects of maxillary sinus floor elevation using the crestal approach technique on sinus mucosal thickening and bone formation in the sinus were evaluated using cone beam computed tomography...

Sinus augmentation is a routine procedure performed in patients presenting with severe atrophy of the posterior maxillary alveolar ridge who seek dental implant surgery. Although this strategy is successful in large part, complications such as maxillary sinusitis, antral bleeding, resorption of graft material, infection, failure of implant installation, and oroantral fistula formation are documented on occasion. However, reports of postoperative maxillary cyst (POMC) arising after sinus augmentation are rare...
