Numerous grafting materials have been used to augment the maxillary sinus floor for long-term stability and success for implant-supported prosthesis. To enhance bone formation, adjunctive blood-born growth factor sources have gained popularity during the recent years. The present study compared the use of platelet-rich fibrin (PRF) and bovine-autogenous bone mixture for maxillary sinus floor elevation. A split-face model was used to apply 2 different filling materials for maxillary sinus floor elevation in 22 healthy adult sheep...

INTRODUCTION: Authors describe and analyze an implant-prosthetic rehabilitation of posterior partially edentulous jaw by using a super-short implant, according to the platform switching technique, on which a lithium disilicate made crown was cemented. METHODS: One event of partially edentulous jaw in 2.6 region needing implant-prosthetic rehabilitationwas selected for this treatment. Because of the lack of vertical bone, a super-short implant (6mm in diameter and 6mm in length) has been placed according to the platform switching technique by using surgical and prosthetic components lower in diameter compared to the diameter of the implant's platform...

BACKGROUND: Present clinical practice broadly relies on off-the-shelf allogeneic, xenogeneic or synthetic bone biomaterials in support of sinus augmentation. Also, recombinant human bone morphogenetic protein-2 in an absorbable collagen sponge carrier (rhBMP-2/ACS) has been shown to support clinically relevant bone formation when used to augment the maxillary sinus. OBJECTIVES: To evaluate local bone formation/dental implant osseointegration following implantation of two particulate bone biomaterials using the mini-pig sinus augmentation model...

A minimum subantral bone height in the posterior maxilla may require a bone augmentation where a sinus lift procedure is the most commonly used technique, either preceding or simultaneously with the implant installation. While elevating the Schneiderian membrane ruptures are common, possibly resulting in less bone formation. In this paper, we propose the surgical pneumatization of the Schneiderian membrane as a new technique to minimize the risk of such complications. This can be achieved mainly by creating a hole for the immediate and increased passage of air through the Schneiderian membrane and the maxillary sinus wall above the region of augmentation...

BACKGROUND: Few studies have been conducted to assess new bone formation using Biogran, a bioactive glass, in maxillary sinus bone augmentation through a prospective and randomized evaluation. Moreover, there are no studies that evaluate cellular behavior by immunohistochemical assessment for osteoblastic and vascular activity during bone repair. PURPOSE: The aim of this study is to compare new bone formation and cellular behavior with Biogran alone, a 1:1 combination of Biogran and autogenous bone graft, and autogenous bone graft alone in human maxillary sinuses...

OBJECTIVE: The aim of the present split-mouth study in sheep was to assess the influence of in situ hardening properties of a biphasic calcium phosphate bone graft substitute (ratio HA/β-TCP = 60/40) compared to a particulate bone graft substitute with the same biphasic core-granule composition without in situ hardening properties on sinus floor augmentation. MATERIAL AND METHODS: Therefore, bilateral sinus floor augmentation was performed in eight sheep. PLGA coated, in situ hardening biphasic bone graft substitute (PLGA-NMP-BCP) was placed into the test site and a particulate biphasic bone graft substitute without PLGA coating (BCP) was used for the contralateral site as a control...

BACKGROUND: Implant failures are more common when multiple missing posterior teeth need lateral sinus floor elevation owing to inadequate tissue maturation after grafting. Effects of lateral window dimensions on vital bone formation have rarely been compared. PURPOSE: To compare endo-sinus bone formation between two- and solo-window techniques to rehabilitate multiple missing posterior teeth that need substantial augmentation. METHODS AND MATERIALS: Patients with severely atrophic posterior maxilla were randomized to receive lateral sinus floor elevation via solo or two bony windows...

The purpose of this investigation is to evaluate 2 different methods for reducing cortical wall thickness in sinus floor augmentation surgery. A manual bone scraper was compared in terms of efficacy, speed, and safety to an ultrasonic insert for osteoplasty, in a randomized controlled clinical trial with a split-mouth design. Twenty-five patients with severe posterior maxillary atrophy were treated with bilateral sinus floor elevation with lateral approach. Antrostomies were randomly performed by eroding the cortical wall with a manual bone scraper (test site) or with an ultrasonic insert (control site) until the membrane was visible under a thin layer of bone, before outlining the window with a piezoelectric device...

With the aim to obtain an injectable bioactive scaffold that can accelerate bone formation in sinus lift augmentation, in bony void and in fracture repair, we have developed a three-dimensional (3D) jelly collagen containing Lysophosphatidic acid (LPA) and 1α,25-Dihydroxyvitamin D3 (1,25D3). Using an in vitro 3D culture model of bone fracture we show that the contraction of the collagen gel is mediated by Rho-kinase activation in osteoblasts. This contraction was cell concentration dependent and was increased by LPA which favored apposition and fastening of bone fragments approach...
