Techniques in Complete Denture Technology 1st Edition – Preface

As the dental profession becomes more successful in delaying complete edentulism
in patients until much later in their lives, it also brings with it greater problems in
providing these older patients with satisfactory complete dentures.

More understanding of all aspects of complete denture provision will be needed to achieve
satisfactory outcomes for these patients. The technical aspects of complete denture provision are very often given brief consideration in publications relating to complete denture provision. This side of complete denture provision, however, often has a major impact on the success or failure
of the dentures.

This book is intended for all student dentists and technicians, clinicians, clinical
dental technicians and technicians who have an interest in complete denture provision, with the hope that it may stimulate new ideas and improve technique when considering the technical aspects of denture construction.

We would like to thank the following people who either provided or modelled for the pictures that appear in this text. First we thank Mr Peter Bridgwood for kindly allowing the use of his image and Dr Hannah Barnes for providing clinical pictures.

We also appreciate the help given by David Wildgoose, Eleanor Stone, Laura Peacock, Sebastian Wilkins, Micheal Spencer, Daniel Leung, Lisa Smith, Christopher Povey and Anna Burrows.

INTRODUCTION

This text will set out the ideal properties of complete dentures, and provide you with
techniques for achieving these when carrying out any stage in the production process. Dentures should function well and look good. The denture wearer may value function over aesthetics or vice versa, but failure to establish a minimal requisite will lead to disappointment.

What do we mean by function well? Dentures should be comfortable, retentive,
stable when biting together in any position, and restore the speech. What do we mean by look good? Dentures should replace the teeth and the resorbed bone, resulting in natural looking anterior teeth, support of the soft tissues and restoration of any loss in vertical dimension.

Establishing function and aesthetics may be challenging in some cases, this text aims
to provide the solutions to ensure the reader understands and can provide the
various elements that are essential for optimum denture provision. This text will help
the reader evaluate, design and provide the following requirements.

Fit:  This is a result of impression technique, impression materials, model materials,
processing method, denture base material and final fitting. Retention:  This results from fit and forming a border seal. Providing retention may prove difficult for lower dentures where stability and muscular control must be optimised to compensate.

Stability is dependent upon fit and occlusion.  Establishing a balanced occlusion is
key to maintaining stability and in turn the border seal. Lower dentures are particularly vulnerable to instability as a result of poor retention. Here the occlusal table should be designed to provide optimum load distribution in order to seat the denture.

Occlusion of the denture teeth  may be established as a conventional balanced
occlusion or as a lingualised scheme, each should result in multiple tooth contacts
around the denture, providing stability in any position.

Muscular control  provides long-term retention of the denture and is aided by the
positioning of the teeth in the neutral zone and by the considered shaping of the
polished surfaces of the denture…….
