BACKGROUND: Zirconium - a bioinert metal - in comparison with titanium implants, offers a variety of potential advantages for use in the esthetic area of dentistry due to its tooth-like color. Zirconium dental implants are considered to be an alternative method of treatment to conventional titanium dental implants for patients with a thin gingival biotype. OBJECTIVES: This study was designed to study the bone tissue response to new zirconia implants with modified surfaces in comparison with commercially available titanium dental implants and commercially available zirconia implants...

The purpose of this case series was to assess safety and feasibility of a novel resorbable collagen matrix (CMX) to enhance tissue thickness simultaneous with implant placement and guided bone regeneration (GBR) in esthetic sites over an 8-week healing period. Soft tissue thickness at implant sites and adjacent teeth was monitored with an ultrasonic device. Overall tissue contour changes were assessed by sequential digital surface model superimpositions. Periodontal parameters and patient-related outcomes revealed no significant changes...

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...

The objective of this study was to present a novel procedure for cortical bone repositioning (CBR) that maintains a secure space under the periosteum by replacement of the lateral cortex via fixation, employing titanium screws. Seven systemically healthy patients presenting with horizontal alveolar bone defects in radiographs and CT images were enrolled for CBR technique for horizontal alveolar bone augmentation. A lateral cortical bone block was cut in the defects and freed from the original bony surface. A screw was inserted into the block, and the block was placed laterally to allow fixation...

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...

Criteria for successful implants, in the rehabilitation of a single missing tooth in the esthetic area, should be determined by composite outcomes, including functional and esthetic aspects of soft tissues and the reconstruction, as well as patient-reported outcomes. This paper focuses on current methods in esthetic assessment and patient-centered/reported outcomes in single-tooth implant rehabilitation in the esthetic area. The relationship between subjective, patient-based esthetic evaluations and objective, professional-based esthetic evaluations is reviewed...

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...

Patient expectations from implant treatment have changed over the years and esthetics plays an important role in defining what is now called success of rehabilitation. Of the many factors that influence the outcome of the rehabilitation, the two main ones are the bone and soft-tissue deficiencies at the intended implant site. Many surgical approaches are described in terms of timing of implant placement and management of regenerative procedures. The aim of this article is to discuss the different implant placement alternatives in the esthetic area, in particular: (i) the timing of implant placement/regenerative procedures/skeletal growth/altered passive eruption; (ii) the correct three-dimensional position of the fixture between the cuspids and in the premolar area; (iii) multiple missing teeth in the esthetic area with single tooth/pontic or cantilevered options/prosthetic compensation; (iv) placement of implants into infected sites; and (v) the influence of abutment and crown morphology on implant position...

Background: Chronic periodontitis in lower anterior teeth results in rapidly progressive gingival recession (GR), loss of alveolar bone, decreased vestibular depth (VD) with consequential tooth mobility, and tooth loss. Treatment option for such cases in this esthetically important area of the oral cavity includes extraction followed by implants for which sufficient bone height and mucogingival complex are a prerequisite. Henceforth, an attempt was made to prolong the life of lower anterior teeth and postpone the need for implants by the treatment of chronic periodontitis with periodontal flap surgery followed by vestibular deepening in single surgical procedure...

This case series describes a treatment method in which the natural tooth was used as the temporary and permanent reconstruction after immediate implantation in the esthetic zone of periodontally compromised patients. Five patients with a hopeless tooth in the esthetic zone due to periodontal causes were included. The tooth was extracted, and immediate implantation protocol was followed. The extracted tooth was adapted over a temporary abutment during the osseointegration period, and the same tooth served as the final prosthetic reconstruction with a customized zirconia abutment...

Occlusal and esthetic rehabilitation of jaw deformities in patients with partially edentulous maxilla are challenging procedures. This article describes a patient involving a skeletal Class III, 36-year-old male patient with a single bilateral anterior partially edentulous maxilla resulting from injuries sustained in a motor vehicle accident; his anterior teeth had been lost for more than 10 years. His lip protruded from the lateral view due to the proclined upper incisors and mandibular protrusion.Because of the facial deformity and inadequate prosthesis of the maxilla, the prosthesis had dropped out repeatedly...

Demographers agree that the so-called elderly population will increase steadily in the future. Not only will their numbers increase, but they will live to an older age. In the case of fully edentulous patients, implant treatment is a possibility, but for many, rehabilitation by means of full removable dentures is still the preferred option. In recent decades, computer-aided design/computer-aided manufacturing (CAD/CAM) has brought about what can only be described as a revolution in dental offices and dental laboratories...
