Prospective evaluation of immediate and delayed provisional single tooth restorations.

Purpose: The purpose of this study was 2-fold: to determine whether there is a significant difference in the hard and soft tissue response comparing immediate with delayed implant placement after tooth removal, with immediate provisionalization, in maxillary anterior sites; and to determine and compare the crestal bone levels as the primary endpoint variable for implants placed and immediately temporized in extraction sites, to implants placed into extraction sites after the extraction site has been grafted and healed for 4 months, all immediately restored with an anatomic provisional restoration. This aim was to be evaluated by measuring crestal bone levels on standardized digital radiographs of the implants, using implant threads as a monitor of magnification and a pre-extraction reference. Secondary endpoint variables include soft tissue measures compared with method.

Replacement of a fixed partial denture secondary to abutment fracture.

Background: The authors present a case that demonstrates the efficient replacement of a fixed prosthesis after a patient's abutment tooth fractured and required extraction. The fractured tooth had a local infection, and the maxillary bone was low-density and limited in height.

Case Description: The authors removed the tooth and grafted the site with particulate bone, while concurrently placing two implants in the edentulous region.

Techniques to facilitate provisionalization of implant restorations.

Purpose: The aim of this article was to review current methods for immediate provisionalization of single unit implant restorations.

Methods: Four methods are discussed and illustrated in detail, including: preoperative preparation of an abutment and provisional crown using diagnostic models; abutment placement and modification at the time of implant placement; the use of 1-piece or non-prepable abutments; and methods of indexing. Material characteristics for indexing are presented to provide the clinician with an understanding of material handling in relation to accuracy of indexing.

Treatment planning for multiunit restorations--the use of diagnostic planning to predict implant and esthetic results in patients with congenitally missing teeth.

Patients afflicted with congenitally missing teeth are a unique patient population for consideration of treatment with osseointegrated implants. Frequently, these patients have limited development of the alveolar process and differences in spatial position relative to the opposing arch, which places emphasis on ancillary treatment with orthodontics and oral surgery. A thorough diagnostic workup should include an interdisciplinary approach to ensure optimal treatment and timing of treatment in those who are developing.

Using ParaPost Tenax fiberglass and ParaCore build-up material to restore severely damaged teeth.

This article describes a technique using ParaPost Tenax Fiber White, ParaPost Cement, and ParaPost ParaCore build-up material to restore a tooth with a significant loss of tooth structure. After successful root canal therapy, the posts were bonded in the canals and the core was built using ParaPost ParaCore build-up material. At that point, the tooth was prepared to receive a conventional porcelain-fused-to-metal crown.

Shear bond strength of four core materials to dentin bonded with light-cured or dual-cured adhesive.

Purpose: To measure and compare the shear bond strength of four core materials to dentin bonded with one adhesive (Prime and Bond NT) that was either light-cured or dual-cured.

Methods: The dentin of 80 freshly extracted molars was exposed using a series of abrasive disks. The teeth were divided into eight equal groups, etched with phosphoric acid for 15 seconds and rinsed.

Immediate loading of dental implants in the edentulous mandible.

Background: The authors review the literature regarding immediate implant loading in the anterior edentulous mandible, demonstrate the technique they currently use, review preliminary results and present an illustrative case.

Materials And Methods: The authors conducted a literature search using PUBMED and Ovid databases. They considered for review 31 articles in English from 1969 to 2003 that pertained to immediate loading of the anterior mandible.

Single tooth immediate provisional restoration of dental implants: technique and early results.

Purpose: Patients desire efficient restoration of missing teeth. Immediate provisionalization of implants at the time of placement can provide the patient with a tooth-like restoration. Our hypothesis is that preoperative fabrication of the implant abutment and provisional restoration can provide successful immediate provisionalization of implants, if specific diagnostic criteria are used for patient selection.

Immediate loading of the edentulous mandible: delivery of the final restoration or a provisional restoration--which method to use?

Purpose: Edentulous patients desire restoration of their chewing ability as soon as possible after placement of dental implants. The purpose of this article is to provide clinicians with evidence that immediate loading of implants placed into the anterior mandible can predictably provide the patient with early functional rehabilitation. Two methods are presented that illustrate delivery of the final restoration or a provisional implant-borne prosthesis immediately after implant placement.

Immediate implant placement and provisionalization using implants with an internal connection.

Single-tooth implant restoration has evolved from traditional two-stage surgical procedures to techniques that allow implant placement and provisionalization immediately following tooth extraction. Restorative success using an immediately provisionalized implant system is based upon adherence to several clinical and biological parameters. This article will discuss the clinical and restorative considerations that must be addressed when immediately loading single-tooth implants.

Immediate Dental Implant Placement in Sockets Augmented With HTR Synthetic Bone.

Purpose: The purpose of this article is to present the results of using immediate implant placement in combination with HTR synthetic bone socket grafting to achieve a predictable restorative result.

Material And Methods: Twenty-three hydroxylapatite-coated cylinder implants (Spline, CenterPulse Dental, Carlsbad, CA) were placed into fresh extraction sockets in 19 patients. In each case, HTR synthetic bone (Bioplant, Inc.

The evolution of external and internal implant/abutment connections.

The indications for implant dentistry continue to increase, enabling the restoration of partially and totally edentulous patients with greater success and predictability. Recent goals for implant dentistry include simplifying the involved procedures, reducing the duration of therapy for the patient and clinician, and enabling the use of conventional prosthodontic techniques for implant-supported restorations. This article reviews key developments in implantology and highlights the various design characteristics of internal abutment connection implants, demonstrating their clinical application in a detailed case presentation.

All-ceramic restorative system for esthetic implant-supported crowns: in vitro evaluations and clinical case report.

Patient demands for improved esthetics have prompted the development of all-ceramic restorative systems for dental implants, but material strength and restorative costs have presented clinical challenges. Therefore, a new restorative system with tooth-shaped ceramic copings for the anterior and premolar jaw regions has been introduced to address these problems. Fatigue and 17o.

Evaluation of hard tissue replacement composite graft material as a ridge preservation/augmentation material in conjunction with immediate hydroxyapatite-coated dental implants.

Background: Immediate placement of dental implants (DI) in fresh extraction sockets is associated with remaining voids around the DI and often a partial dehiscence or thin facial alveolar plate. Bone replacement grafts are often used to correct these problems. This study evaluated the use of a layered composite of PMMA (poly-methyl-methacrylate), PHEMA (poly-hydroxyl-ethyl-methacrylate), and calcium hydroxide grafts (HTR) as a ridge preservation/ augmentation material used in conjunction with an immediate DI placement technique.

Use of HTR synthetic bone as an augmentation material in conjunction with immediate implant placement: a case report.

Immediate placement of dental implants (DI) in fresh extraction sockets is associated with remaining voids around the DI and often a partial dehiscence or thin facial alveolar plate. Bioplant HTR synthetic bone (HTR) was used as a ridge preservation/augmentation material in conjunction with this method of DI placement. A 61-year-old white woman requiring extraction of tooth 12 opted for immediate DI placement.
