Biofunctional Prosthetic System Normal Bite

Introduction

This full arch prosthetics course focuses on the restoration of the Class I, II and III edentulous arch. Although the course will discuss the function of the temporomandibular joint, it will pay particular attention to the direction movements of the mandible that are dictated by the teeth.

As a tool to simulate the movements of the mandible, the Stratos articulator introduces a much higher level of perception when creating full arch prosthetics. You can literally feel the movements through your fingertips. According to the theories of Dr Rainer Strack (1912-1969), SR Orthosit teeth are constructed to take into account the natural excursions of the mandible.

Master dental technician Eugene Schlaich modelled the Ivoclar Vivadent tooth moulds in 1959-1963, and these remain the market leading teeth today. This extensive range of functional posterior teeth accommodates even the most awkward of bite types. When used correctly in ‘posterior group function’ these posterior teeth will operate in a contacted slide on the working and balancing side surfaces.

Overview

This course discusses teeth that are designed to compensate for the mandibular movements when set to the sagittal compensation Curve of Spee and the Transversal compensation Curve of Wilson (Spee of Monson).

T- moulds: Deep bite occlusion - a protruding maxilla and retracted mandible with deep overbite

K- moulds: Cross bite occlusion - a protruding mandible and retracted maxilla

N- moulds: Normal occlusion - numerous variations

Anterior A-moulds: designed according to several selection methods -

Shape of patient's head

Anatomy of the body

Patient's gender

Often, no information is provided on the laboratory prescription. On this course, we demonstrate a method for tooth selection according to the maxilla and its anatomical reference points.

What's more, we will undertake a thorough model analysis of each case in order to facilitate the setting of the anterior teeth, often referred to as the Biogenic set up. With this technique, we will support your understanding of the resorption of the alveolar processes and the three broad geometric categories of the overall alignment of the dental arch: ovoid, square and tapered, which can be seen in numerous variations and their relationship to tooth shape.

In addition, the course lecturers will demonstrate a method for producing an anatomic wax to compliment the anterior denture teeth, providing the aesthetic effect that the teeth literally grew into place. Furthermore, they will discuss how your personal touch and creativity makes each BPS denture as unique as the patient who wears them.

Aims and Objectives

• Understand tooth dominance (individual and grouped)
• Understand denture tooth dimensions (individual and grouped)
• Understand denture tooth axis - the progression of distal inclination of the anterior teeth
• Understand tooth graduation - the principles of graduation of size and bilateral progression in size and shape of the denture teeth from the central incisor to the most visible posterior tooth
• Understand the use of idela reference points for full arch prosthetics - median plane, horizontal plane, campers plane, Bonwill Triangle and Balkwill angle
• Understand model analysis for full arch prosthetics - learn the stable reference points important for the restoration of the full arch using complete dentures
• Understand the wear patterns in posterior teeth for various skeletal classifications
