INTRODUCTION: After implant placement, a stress-free healing period of 3-6 months is a pre-requisite to achieve good osseointegration. If this duration could be reduced, the patients would feel happier. Eventhough, immediate loading of implants is a clinically feasible concept; it is not possible in certain situations. Few studies have shown that Static magnetic field is useful to promote bone formation faster after the bone is wounded. AIM: This pilot study was intended to evaluate the tissue response after implant placement under the influence of magnetic field...

AIM AND OBJECTIVES: Edentulism is an incapacitating and irretrievable condition which can lead unswervingly to functional limitation, physical, psychological and social handicap. Maintenance of bone after tooth loss to improve retention, function, and performance of the restoration is a challenging task. The existence of a thin edentulous ridge signifies a clinical situation that is more complex for the placement of endosseous implants. Dental rehabilitation of the edentulous ridges with oral implants has become a routine treatment modality in the last few decades with consistent long term results...

The routine use of antibiotics in oral implant treatment seems to be widespread. The pre- or post-operative use of antibiotics in conjunction with implant surgery and its correlation with failure and success rates are poorly documented in the literature. The debate regarding overprescription of antibiotics raises the need for a critical evaluation of proper antibiotic coverage in association with implant treatment. The benefits of prophylactic antibiotics are well-recognized in dentistry. However, their routine use in the placement of endosseous dental implants remains controversial...

The field of dentistry is an ever-evolving discipline. A marked rise in the use of endosseous implants, adhesive ceramic bonding, and composite resins, as well as continued patient desire for minimally invasive procedures, has created a new conservative era in the practices of many restorative dentists. These trends, coupled with the significant financial impact associated with the reconstruction of failing, worn, and esthetically compromised dentitions, have facilitated a paradigm shift in the way that individual patient cases are being treatment planned today...

PURPOSE: Reconstruction of hard tissue continuity defects caused by ablative tumor surgery has been traditionally reconstructed with autogenous bone grafts or microvascular free flaps. Although results have been predictable from these 2 methods of reconstruction, the morbidity associated with bone harvest is quite serious for the patient. Predictable results have been obtained with using a combination of 100% cadaver bone, bone marrow aspirate concentrate (BMAC), and recombinant human bone morphogenic protein in immediate reconstruction for benign tumor extirpations through the extraoral approach...

Many treatment modalities have been introduced for correction of deficient alveolar ridge width. Bone expansion through the ridge split procedure is one of them. This technique was initiated in order to overcome many problems that usually associated with grafting procedures. The present study evaluated the effectiveness of piezoelectric device in performing ridge split using single-stage approach and assessed the outcomes during a period of about 4 months after surgery. A total of 23 patients ages in range between 18 and 60 years underwent ridge split procedure with immediate insertion of dental implants...

For several decades, titanium and its alloys have been commonly utilized for endosseous implantable materials, because of their good mechanical properties, chemical resistance, and biocompatibility. But associated low bone mass, wear and loss characteristics, and high coefficients of friction have limited their long-term stable performance, especially in certain abnormal bone-metabolism conditions, such as postmenopausal osteoporosis. In this study, we investigated the effects of platelet-rich plasma (PRP) treatment and TiO2 nanoporous modification on the stability of titanium implants in osteoporotic bone...

Ceramic dental materials, especially alumina (20 %vol)-yttrium stabilized tetragonal zirconia poly crystal (A-Y-TZP20), have been considered as alternatives to metals for endosseous dental implant application. For increasing the bone-to-implant contact as well as the speed of bone formation, a new surface modification can be effective. The aim of this study was to design microgroove patterns by femtosecond laser on A-Y-TZP20 nano-composite disks for endosseous dental implant application. The phase composition and the morphology of the A-Y-TZP20 nano-composite samples were characterized using X-ray diffraction and Scanning electron microscopy equipped with energy dispersive X-ray spectroscopy techniques...

Epidermolysis bullosa (EB) is a rare disease affecting the skin and mucus membranes, which is characterized by the formation of blisters in response to minimum trauma. The use of endosseous implants for fixed prosthetic restoration in patients with Recessive Dystrophic Epidermolysis Bullosa (RDEB) provides considerably better results than conventional methods using removable dentures. The objective of this clinical case is to describe the restoration of the full arch of an atrophic maxilla using endosseous implants and an implant-supported fixed prosthetic in a patient diagnosed with RDEB and exhibiting severe general and oral symptoms; and to evaluate improvements in the quality of life of the patient...

The use of zirconia in medicine and dentistry has rapidly expanded over the past decade, driven by its advantageous physical, biological, esthetic, and corrosion properties. Zirconia orthopedic hip replacements have shown superior wear-resistance over other systems; however, risk of catastrophic fracture remains a concern. In dentistry, zirconia has been widely adopted for endosseous implants, implant abutments, and all-ceramic crowns. Because of an increasing demand for esthetically pleasing dental restorations, zirconia-based ceramic restorations have become one of the dominant restorative choices...

A fractured abutment screw of a crown supported by an endosseous implant is a complication. The fragment in the fixture can be retrieved with a festooned #557 latch burr set in reverse torque and subsequent clockwise turning #33 1/3 burr touched to the fragment side. The cemented abutment and crown can be salvaged by heating the crown/coronal screw fragment to 1000 degrees C for 20 minutes. Upon cooling, the crown and abutment can be then separated. A new abutment screw can then be used. The patient's diet, occlusal scheme and maximal bite force should be assessed...

Treatment of osseous defects remains a formidable clinical challenge. Porous titanium alloys (pTi) have been emerging as ideal endosseous implants due to the excellent biocompatibility and structural properties, whereas inadequate osseointegration poses risks for unreliable long-term implant stability. Substantial evidence indicates that pulsed electromagnetic fields (PEMF), as a safe noninvasive method, inhibit osteopenia/osteoporosis experimentally and clinically. We herein investigated the efficiency and potential mechanisms of PEMF on osteogenesis and osseointegration of pTi in vitro and in vivo...

Bone-forming cells and Mϕ play key roles in bone tissue repair. In this study, we prepared a superhydrophilic titanium implant functionalized by ozone gas to modulate osteoconductivity and inhibit inflammatory response towards titanium implants. After 24 h of ozone gas treatment, the water contact angle of the titanium surface became zero. XPS analysis revealed that hydroxyl groups were greatly increased, but carbon contaminants were largely decreased 24 h after ozone gas functionalization. Also, ozone gas functionalization did not alter titanium surface topography...

BACKGROUND: Calcium phosphate (CaP) surface coatings may accelerate osseointegration and serve as a drug delivery system for mineral-binding biomolecules. In a pilot study, the impact of a commercially available, thin CaP coating on early osseous bone remodeling was compared with a modern, subtractive-treated rough surface (SLA-like) in an animal trial. METHODS: In 16 rabbits, 32 endosseous implants (CaP; n = 16, SLA-like; n = 16) were bilaterally inserted in the proximal tibia after randomization...
