Retention forces of spherical attachments as a function of implant and matrix angulation in mandibular overdentures: An in vitro study
Nonparallel implants, when used to retain overdentures, may present a restorative challenge, particularly when using attachments.
Premature wear of the components and loss of retention may be observed, resulting in increased maintenance.
Purpose: The purpose of this study was to compare the retentive behavior, over time, of spherical attachments when used in nonparallel and parallel implant scenarios in a cyclic testing mode.

A hollow delayed surgical obturator for a bilateral subtotal maxillectomy patient: A clinical report
Effective obturation of the bilateral maxillectomy defect is a difficult task for the maxillofacial prosthodontist.
Multidisciplinary treatment planning is essential to achieve adequate retention and function for the prosthesis.
This clinical report describes an original technique of engaging the inner aspect of the nasal aperture to augment anterior retention of a hollow obturator in a bilateral subtotal maxillectomy defect.
This method is simple to execute, and may be used chairside for a surgical, interim, and/or definitive obturator. (J Prosthet Dent 2008;99:14-18).

Preparation Sequence of a 3-Unit Fixed Partial Denture
This video illustrates a straightforward tooth preparation sequence for a 3-unit fixed partial denture where reduction accuracy and preparation draw are emphasized through the use of reduction guides and paralleling grooves.
The demonstration is recorded on a typdont with Ivorine teeth using carbide and diamond burs.
The video depicts the step by step preparation process taught by the Prosthodontics Department at The University of Texas Dental Branch at Houston to dental students, Prosthodontics residents and preceptors.

Techniques for incorporation of attachments in implant-retained overdentures with unsplinted abutments
A variety of techniques have been reported in the literature for the incorporation of attachments in implant-retained partial and complete overdentures with unsplinted or individual abutments.
Three important elements that are necessary in describing any technique for incorporation of attachments are the type of final impression method (tissue-level impression, abutment-level impression, or implant-level impression), stage of overdenture fabrication (record base stage, denture-processing stage, or denture insertion stage) and nature of technique (direct or indirect).
This article reviews 7 different techniques for the incorporation of attachments in implant-retained complete and partial overdentures.
Discussion of indications, contraindications, advantages, and disadvantages of each technique is provided to aid the clinician in making an appropriate choice.
