The purpose of this study is to offer a novel kind of polyurethane with improved surface blood compatibility for long-term implant biomaterials. In this work, the aliphatic poly(ester-urethane) (PEU) with uniform-size hard segments was prepared and the PEU surface was grafted with hydrophilic poly(ethylene glycol) (PEG). The PEU was obtained by chain-extension of poly(ɛ-caprolactone) (PCL) with isocyanate-terminated urethane triblock. Free amino groups were introduced onto the surface of PEU film via aminolysis with hexamethylenediamine, and then the NH2 -grafted PEU surfaces (PEU-NH2 ) were reacted with isocyanate-terminated monomethoxyl PEG (MPEG-NCO) to obtain the PEG-grafted PEU surfaces (PEU-PEG)...

OBJECTIVE: Loss of teeth frequently results in compound horizontal and vertical alveolar bone defects. An appropriate bone structure is the key for implant placement and bony support of soft tissues. Advanced bone augmentation techniques are required for the reconstruction of these defects. This report will present a new bone block grafting technique with 12-month follow-up. METHOD: The seedling technique was used to augment the alveolar bone 3-dimensionally with autologous bone block and an osseointegrated implant in a 2-stage procedure...

Staphylococcus aureus is a Gram-positive opportunistic pathogen that causes superficial and invasive infections in the hospital and community. High mortality from infection emphasizes the need for improved methods for prevention and treatment. Although S. aureus possesses an arsenal of virulence factors that contribute to evasion of host defenses, few studies have examined long-term humoral and B-cell responses. Adults with acute-phase skin and soft tissue infections were recruited; blood samples were obtained; and S...

Submuscular gluteal augmentation is a very valid plane for buttocks implantation, even more so in North America, where surgeons can only use silicone elastomer implants. Irrespective of how soft elastomer implants are made, they are much firmer than the silicone gel implants that can be used in other countries. A deeper plane with more soft tissue coverage provides more natural results, as long as the anatomic boundaries are respected. Proper patient and implant selection is the key factor for satisfactory gluteal contours and outcomes...

Achieving excellence in anterior rehabilitations requires close cooperation between the periodontist and the prosthodontist. Many techniques can be used to restore the lost alveolar hard and soft tissues. The more severe the peri-implant defect, the higher the challenge and lower the predictability of the procedure. The present case consists of Seibert class III with mal-aligned implants in the esthetic zone resolved with a cost-modified treatment plan to re-establish esthetics in the anterior maxilla using rotated palatal flap...

BACKGROUND: Bony defect situations are a common problem in revision arthroplasty of the shoulder and are the cause of the complexity of the procedure. Aseptic and septic loosening as well as difficult implant removal can result in humeral and/or glenoid bone loss. PLANNING: A careful preoperative imaging is needed to estimate the extent of the bony defect and to enable precise planning of the bone reconstruction and the required implants. However, the size of the defect needs to be re-evaluated intraoperatively after removal of the implant components and any larger defects have to be addressed appropriately...

PURPOSE: Revascularization of natural and synthetic scaffolds is a critical part of the scaffold's incorporation and tissue ingrowth. Our goals were to create a biocompatible polymer scaffold with 3D-printing technology, capable of sustaining vascularization and tissue ingrowth. METHODS: We synthesized biodegradable polycaprolactone fumarate (PCLF) scaffolds to allow tissue ingrowth via large interconnected pores. The scaffolds were prepared with Poly(lactic-co-glycolic acid)(PLGA) microspheres seeded with or without different growth factors including VEGF,FGF-2, and/or BMP-2...

Periodontal plastic surgery comprises an increasing part of clinical periodontology. Clinical trials have traditionally used professionals to judge esthetic outcome, and few studies have addressed patient needs and requests (true end points). Development of universally accepted and validated methods for professional esthetic assessment, together with standardized questionnaires for patient-perceived outcome, may help to provide better insights into the true needs and benefits of periodontal and implant-associated plastic surgery...

A 36-year-old woman with good periodontal health sought treatment for a compensated Class II partially edentulous malocclusion associated with a steep mandibular plane (SN-MP, 45°), 9 missing teeth, a 3-mm midline discrepancy, and compromised posterior occlusal function. She had multiple carious lesions, a failing fixed prostheses in the mandibular right quadrant replacing the right first molar, and a severely atrophic edentulous ridge in the area around the mandibular left first and second molars. After restoration of the caries, the mandibular left third molar served as anchorage to correct the mandibular arch crowding...

OBJECTIVE: To review the dental literature in terms of soft tissue augmentation procedures and their influence on peri-implant health or disease in partially and fully edentulous patients. METHODS: A MEDLINE search from 1966 to 2016 was performed to identify controlled clinical studies comparing soft tissue grafting versus no soft tissue grafting (maintenance) or two types of soft tissue grafting procedures at implant sites. The soft tissue grafting procedures included either an increase of keratinized tissue or an increase of the thickness of the peri-implant mucosa...

The use of injectable fillers is increasingly popular as an alternative to surgery for facial cosmetic applications. In this regard, silicone is a versatile biomaterial filler that has been used for these purposes, but its use warrants further investigation, especially since it is not clinically approved for such uses. We describe the use of silicone as a facial injectable filler through a scholarly review of the literature for cases of silicone granuloma formation published from September 2007 through September 2017, and we present various contexts in which this complication has been observed...

Comorbidities that negatively impact orthodontic (malocclusion), periodontal (periodontitis, deficient dentoalveolar bone volume, mucogingival), and prosthetic (structural integrity compromise from caries, attrition, and erosion) conditions can affect the general health of the patient. In addition, emerging data highlights the importance of undiagnosed airway volume deficiencies and sleep-disordered breathing conditions in the adult and pediatric population. Deficiencies in dentoalveolar bone and discrepancies in skeletal relationships can impact the volume of hard- and soft-tissue structures of the periodontium and decrease oral cavity volume...

Loss of dentition leads to functional and esthetic challenges that are determined by the anatomic features of the edentulous area. These features can complicate the prosthetic rehabilitation of such patients, especially in situations where optimal esthetic outcomes are desired. For these reasons, reconstructive plastic surgery procedures, aimed at restoring the alveolar ridge to its former dimensions, have become of great clinical interest. These reconstructive plastic surgery procedures frequently involve soft-tissue augmentation, performed to improve the quality and quantity of mucogingival tissue with the aim to achieve an ideal esthetic result...

Diverse clinical advancements, together with some relevant technical innovations, have led to an increase in popularity of tunneling flap procedures in plastic periodontal and implant surgery in the recent past. This trend is further promoted by the fact that these techniques have lately been introduced to a considerably expanded range of indications. While originally described for the treatment of gingival recession-type defects, tunneling flap procedures may now be applied successfully in a variety of clinical situations in which augmentation of the soft tissues is indicated in the esthetic zone...

Achieving symmetry of the soft-tissue margins between anterior maxillary dental-implant restorations and adjacent teeth is a therapeutic challenge for both the implant surgeon and the restorative dentist. This article describes a modified procedure utilizing autogenous connective-tissue grafts to improve primarily buccal soft-tissue margins and secondarily inter-proximal tissues around tooth-bound single dental implants. This technique has the advantage of allowing for coronal augmentation of the peri-implant soft tissue while maximizing the blood supply to the area by using tunneling-technique principles...
