Closed horseshoe major connector

A component of the partial denture that connects the parts of the prosthesis located on one side of the arch with those on the opposite arch. It provides cross-arch stability to help resist displacement by functional stresses.

Closed horseshoe major connector

This document discusses major connectors, which connect the components on one side of a dental arch to the other side. It describes the different types of major connectors for the maxilla, including palatal bars, straps, double palatal bars, horseshoe connectors, closed horseshoe connectors, and complete palates. The functions, advantages, disadvantages, and indications for use of each type are explained in detail. Read less. AI-enhanced description. Download Now Download to read offline.

Class II: A unilateral edentulous area located posterior to the remaining natural teeth Class IV: A single but bilateral crossing the midline edentulous area located anterior to the remaining natural teeth Class I: Bilateral edentulous areas located posterior to the remaining natural teeth. Impingement of gingival tissues is avoided 3. Instead, closed horseshoe major connector, the modified labial bar has a hinge at one end and a locking device at the opposite end.

Federal government websites often end in. The site is secure. The Major connector is the major component of the cast partial denture to which all other parts are directly or indirectly attached. It also provides cross arch stability to help resist displacement by functional stresses. The major connector should be rigid. A flexible major connector causes an unequal distribution of forces with changes in their intensity and may cause damage to the supporting structures. Thus rigidity is of paramount to resist flexing and torquing forces. The commonly used major connectors for the maxillary arch are Anteroposterior strap, palatal strap and complete palatal plate. Application of load on the prosthesis will result in deflection. The magnitude and direction of the deflection that the prosthesis undergoes depends on the rigidity of the major connector.

The first requirement of a major connector is rigidity. Other components of a partial prosthesis can only be effective if the major connector is rigid. Flexibility allows forces to be concentrated on individual teeth or edentulous ridges causing damage to those areas. Major connectors must avoid impingement of the free gingival margin. The major connector must never terminate on gingival tissue. In maxillary castings the border of the major connector should be at least 6mm to 8mm from the gingival margin of the teeth and in the mandibular it should be at least 3mm from the gingival margin. Patient comfort should be a consideration when designing the major connector and food traps must be avoided where possible. A maxillary major connector should have a prepared seal along all borders that contacts soft tissue food line. The food line or seal is scribed into the master cast to a depth of 1mm and width of approximately 1.

Split Palatal Plate: - In this design the major connector is cut partially during the wax pattern stage - The cut is made by a sharp scalpel blade at the junction of the edentulous area and the tooth supported area - During loading the denture base will move vertically with equal force on the soft tissues. Email Required Name Required Website. This permits the major connector to have a minimum height of 5 mm and allows 3 mm of space between the gingival margins and the superior border of the bar. Inherently strong, it can be kept relatively thin. The anteroposterior palatal bar in different planes is the preferred design for obtaining maximum stiffness in the maxillary major connector. Mandibular major connectors Dr. Disadvantages: Lacks rigidity It is frequently made either too thin and flexible or too bulky. All other parts of the partial denture are directly or indirectly attached to the major connector. Arun Bosco Jerald. Vibrio cholera disease presentation slide. When large inoperable lingual tori exists. The inferior border of mandibular major connectors should be gently rounded after being cast to eliminate a sharp edge. Disadvantages of non rigid major connectors: 1. Advantages: Rigid with less thickness Good palatal support Strong, L-beam effect Disadvantages: Interference with phonetics and patient comfort in some case.

What is Major Connectors?

All other parts of the partial denture are directly or indirectly attached to the major connector. Preparation of abutment teeth. Even a slightly distorted connector may bring more stress to bear on the abutment 7. This major connector is particularly indicated when numerous teeth are to be replaced, or when a palatine torus is present. It should be rigid. Multi - checkbox Attribute in the Odoo 17 Celine George. Rest and rest seats. Since this configuration offers little interference with normal tongue action. MacGregor- Designing partial dentures 4. Split Palatal Plate: - In this design the major connector is cut partially during the wax pattern stage - The cut is made by a sharp scalpel blade at the junction of the edentulous area and the tooth supported area - During loading the denture base will move vertically with equal force on the soft tissues. Minimization of torque to individual teeth. Should minimize rotation tendencies in function and support the prosthesis.
