The aim of this study was to evaluate the final vertical gain at the deficient anterior maxillary alveolar ridges using onlay bone grafts with titanium mesh versus inlay bone grafting. This was a single institutional randomized comparative clinical trial. The study population included 16 patients, with edentulous anterior maxillary alveolar ridges (40 implant sites) who were presented and treated at the Faculty of Oral and Dental Medicine in Cairo University from September 2013 to August 2015. Selected patients were randomly divided into two equal groups...

The loss of teeth followed by bone resorption often lead to defects in the alveolar ridge, making installation of dental implants difficult. Correction of such bone defects, especially lack of height of the ridge, is a difficult problem for all dental surgeons. This report describes the outcome of treatment after alveolar ridge augmentation in the atrophic posterior maxillary region via segmental sandwich osteotomy combined with placement of an interpositional autograft prior to placement of endosseous implants...

A healthy 72-year-old man presented with retention problems concerning the dentures in his maxilla. On account of extreme resorption, placement of implants without prior bone augmentation was not an option. The proposal was to use autologous bone harvested from the iliac crest. After a healing period of 4 months, a cone beam computed tomography scan was made, following which the virtual implant planning of 6 implants was carried out. With the help of a template supported by osteosynthesis screws, which had already been inserted during the augmentation procedure, the plan was applied to the patient...

PURPOSE: This study aimed to evaluate how as-built electron beam melting (EBM) surface properties affect the onset of blood coagulation. The properties of EBM-manufactured implant surfaces for placement have, until now, remained largely unexplored in literature. Implants with conventional designs and custom-made implants have been manufactured using EBM technology and later placed into the human body. Many of the conventional implants used today, such as dental implants, display modified surfaces to optimize bone ingrowth, whereas custom-made implants, by and large, have machined surfaces...

BACKGROUND/PURPOSE: Osteoporosis, being a homeostatic imbalance, affects the remodeling of bone. Whether this catabolic bone disease influences peri-implant marginal bone remodeling remains unknown so far. The purpose of this study was to evaluate the influence of osteoporosis on peri-implant marginal bone loss (MBL) in postmenopausal women. MATERIALS AND METHODS: In a matched collective, radiographic peri-implant bone level (at baseline and at follow-up examinations) was compared in healthy and osteoporotic women...

Although the biological process of osseointegration is similar in adults and adolescents, implant placement is contraindicated in young patients until bone growth is complete. However, even in adults, significant craniofacial changes may occur over an individual's lifetime, as a result of discrete and continuous dental eruption, vertical soft tissue augmentation, or facial bone growth. After such changes, implants may be in infraocclusion. The present case report describes the long-term follow-up of a dental implant located in the esthetic zone...

Survival of dental implants depends on several factors; soft tissue (ST) management around dental implants is one of the foremost. Several studies have suggested techniques for ST management around dental implants, but none of them has discussed a suitable timetable for this process. This study aimed to review published articles related to the timing of ST management around dental implants and suggest a customized treatment protocol. A search of the PubMed database was conducted; the search was limited to English-language articles published from January 1995 to July 2015 with available full texts...

BACKGROUND: It is still unclear whether enamel matrix proteins (EMD) as adjunct to bone grafting enhance bone healing. This study compared histomorphometrically maxillary sinus floor augmentation (MSFA) with β-TCP/HA in combination with or without EMD in humans. METHODS: In ten systemically healthy patients needing bilateral MSFA, one side was randomly treated using β-TCP/HA mixed with EMD (BC + EMD) and the other side using only β-TCP/HA (BC). After 6 months, biopsies were harvested from grafted areas during implant installation, being histologically and histomorphometrically analyzed...

REVIEW
Zeinab Rezaei Esfahrood, Loghman Ahmadi, Elahe Karami, Shima Asghari
The purpose of this study was to perform a literature review of short implants in the posterior maxilla and to assess the influence of different factors on implant success rate. A comprehensive search was conducted to retrieve articles published from 2004 to 2015 using short dental implants with lengths less than 10 mm in the posterior maxilla with at least one year of follow-up. Twenty-four of 253 papers were selected, reviewed, and produced the following results. (1) The initial survival rate of short implants in the posterior maxilla was not related to implant width, surface, or design; however, the cumulative success rate of rough-surface short implants was higher than that of machined-surface implants especially in performance of edentulous dental implants of length <7 mm...

The purpose of this article was to report the clinical and radiographic findings about a case of a man affected by severely atrophic maxilla to demonstrate the clinical proceedings associated with alveolar reconstruction destined for dental implant rehabilitation. The 3-dimensional augmentation of the alveolar ridge with the use of fresh-frozen bone graft, platelet-rich fibrin membrane, and titanium mesh suggests potential benefits to the development of the bone formation physiology. The treatment combination may result in an optimal prognosis and represents an option for reconstruction of bone defects...

PURPOSE: Precisely designed jaw reconstruction rehabilitation (JRR) is important to the integrity of the jaw structure and oral functions. Advanced three-dimensional (3D) digital surgical design and simulation (SDS) techniques have the potential to reduce time to reconstructive and dental treatment completion, thereby promoting early functional oral rehabilitation. This study investigated the use of SDS in JRR procedures. MATERIALS AND METHODS: A retrospective chart review was conducted on adult head and neck tumor (HNT) participants who completed JRR treatment with a fibular free flap (FFF) reconstruction...

Immediate loading has proven to be a predictable modality for restorations with titanium dental implants. An increasing number of articles indicate that zirconia implants might osseointegrate to a similar extent in this context. This 5-year case report describes an outpatient maxillary restoration with eight immediately loaded zirconia implants. Implantation followed extensive bone augmentation. At the 5-year follow-up, all implants were still well osseointegrated clinically and radiologically. No major bone loss or peri-implantitis had occurred in spite of temporary insufficient patient compliance...

Well-coordinated interdisciplinary dental treatments provide the best esthetic, functional, and long-term results for patients. However, the length of such treatment, which may involve orthodontics, ridge augmentation, and dental implants, often deters patients from pursuing them. The two case reports presented here aim to present the advantage of simultaneous orthodontic molar uprighting and ridge augmentation procedures for future implant site development. Selective decortication of the alveolar bone, performed simultaneously with bone grafting, can accelerate the tooth uprighting process and synergistically reduce treatment duration...

Mandibular ridge augmentation via guided bone regeneration in the atrophic mandible is considered one of the most challenging scenarios for implant-supported oral rehabilitation. Uneventful wound healing has clearly demonstrated its impact on the final regenerative outcome. Soft tissue management must be precise and adequate to attain flap-free wound closure. Accordingly, it demands exhaustive insight and expertise to avoid damaging the neighboring structures. The cadaver study described herein discusses the mandibular morphologic landmarks (ie, musculature, vascularization, innervation, and salivary glands) necessary to safely perform regenerative procedures in the atrophic mandibular ridge, such as vertical ridge augmentation and dental implant surgery...

Renato Luiz Maia Nogueira, Rafael Lima Verde Osterne, Ricardo Teixeira Abreu, Phelype Maia Araújo
An alternative technique to reconstruct atrophic alveolar vertical bone after implant placement is presented. The technique consists of distraction osteogenesis or direct surgical repositioning of an implant-and-bone block segment after segmental osteotomies that can be used in esthetic or unesthetic cases. Initially, casts indicating the implant position are obtained and the future ideal prosthetic position is determined to guide the model surgery. After the model surgery, a new provisional prosthesis is fabricated, and an occlusal splint, which is used as a surgical guide and a device for distraction osteogenesis, is custom fabricated...
