Precision of flapless implant placement using real-time surgical navigation: a case series.

Purpose: To demonstrate the predictability of flapless surgery using navigation surgery.

Materials And Methods: Computer-generated preoperative implant planning was compared to actual placement by CT (computerized tomography) scanning of patients before and after surgery. Once pre- and postoperative coordinates of virtual implants were obtained, linear distances and angles were calculated.

Accurate transfer of peri-implant soft tissue emergence profile from the provisional crown to the final prosthesis using an emergence profile cast.

Background: The use of impression copings to make the final impression results in a master cast in which the soft tissue configuration around the implant platform is circular. Therefore, any soft tissue sculpting developed clinically by the provisional restoration is squandered.

Purpose: The purpose of this report was to present a method for the precise transfer of the peri-implant soft-tissue developed by a customized provisional restoration to an emergence profile cast.

Advanced concepts in implant dentistry: creating the "aesthetic site foundation".

To obtain optimal and predictable aesthetics, deficiencies caused by soft and particularly hard tissue loss can be managed by various methods, such as orthodontic tooth eruption, socket preservation, and guided bone regeneration. However, in complex cases, these methods are often insufficient. Here, the authors introduce advanced concepts in aesthetic implant dentistry, such as "Aesthetic Site Foundation", "Aesthetic Guided Bone Regeneration" and "Implant Rectangle" that will guide the clinician in the quest to optimal aesthetic outcomes.

Unexpected return of sensation following 4.5 years of paresthesia: case report.

Neural damage leads to a transient or persistent alteration, depending on the severity or type of injury sustained. During the last decade, many investigators reported on paresthesia related to dental implants. In this case report, the patient had presented repeatedly with swelling and suppuration, showing typical signs of peri-implantitis.

Distribution of the maxillary artery as it relates to sinus floor augmentation.

Purpose: Knowledge of the blood supply to the sinus is of importance in sinus augmentation, both as it pertains to vascularization of the sinus graft and as its location relates to the position of the required lateral osteotomy. The purpose of this study was to investigate the distribution of the endosseous branches of the maxillary artery in the area of the proposed lateral window.

Materials And Methods: Fifty computerized tomographic (CT) scans from 625 available patients undergoing sinus augmentation surgery at the New York University Department of Implant Dentistry were chosen at random for evaluation.

A comparison of characteristics of implant failure and survival in periodontally compromised and periodontally healthy patients: a clinical report.

Purpose: This study compares implant survival and patterns of implant failure in periodontally compromised and periodontally healthy patients.

Materials And Methods: In a private periodontal practice, over a 13-year period, implants were placed in both periodontally compromised and periodontally healthy patients. Implants were classified in 5 different groups according to surface texture.

Realities and limitations in the management of the interdental papilla between implants: three case reports.

A predictable, aesthetic result is sometimes difficult to achieve when two or more adjacent implants are placed in the anterior maxilla. Maintenance of the distance from the interproximal crest of bone to the contact point influences the presence or absence of the interdental papilla. The design of the coronal portion of implants currently in the market and the contour of the implant-abutment junction may further affect the biology and reformation of the papilla between two adjacent implants.

Regeneration of an osseous peri-implantitis lesion.

This case report concerns the loss of osseous tissue around two hydroxyapatite (HA) Biovent implants, placed in 1993, at sites #30 and #31. The implant in site #31 was positioned with a distal angle, resulting in an ill-fitting prosthesis. This permitted bacterial colonization to set up a periimplantitis.

Immediate loading of osseotite implants: two-year results.

The high success rate of dental implants has changed the quality of life for many patients. Immediate loading finds its application in some clinical cases and certainly adds another modality of treatment for the implant patient. Starting with a couple of implants placed in the mandible and immediately loaded within 72 hours after surgical placement with an overdenture, this concept evolved to immediately loading multiple implants in both the maxilla and the mandible.
