A study of some factors associated with denture retention. the dietary patterns of the individuals increases need of using denture as the teeth decay or loss may occur therefore of careis, periodontal damage and uncontrolled diabetes. cm and mandibular denture bearing area is less 14 sq. FACTORS AFFECTING RETENTION IN COMPLETE DENTURE 2. Now a days.the dietary habits of the people increases need of using denture as the tooth decay or loss may occur as a result of careis,periodontal destruction and uncontrolled diabetes.In order to achieve success in treatment,some of the matters should be considered.In complete denture,the attitude and motivation of the patient should be evaluated.The dentist should know about the patient’s problem and demands and keeping in mind try to meet expectations.The whole procedure in the fabrication of complete denture including problems in retention,support and stability of denture must be explained to the patient.After this the dentist must work with the patient to get success in matters such as speech,mastication,esthetics and neuromascular control.By solving pateints complain positively,dentist can satisfy the patient and even train the patient to solve their problems in future.At last,it is the duty of dentist to inform patient that the success of complete denture depends on the maintainance of denture at home as well as giving regular visits to dentist. mandibular complete denture and this is mostly due to lack of retention. Retention depends upon numerous factors such as physical, physiological, psychological, mechanical, and surgical factors. *** Veterans Administration Hospital, Castle Point, N. Y. The viscosity of saliva plays an important role in a sepration of two surfaces after the force is applied.The viscosity of saliva is not under control and is time dependent.The viscous material is useful in denture retention to some extent as washing of it with time can reduce efficacy. Stability is the prevention for denture base to move in a horizontal direction and from sliding front or back and side to side.It is more important in lower complete denture.If the ridge is higher and broader than there will be better stability. Dr. Chetan. Antolion C, Kotwal K, Mangelsdorff D. Analysis of posterior palatal seal and the palatal form as related to the retention of complete dentures. Thus the retention is produced because of draw and displacement. Unfortunately, the physical, physiologic, and mechanical factors associated with denture retention are not completely understood. Stability is the prevention for denture base to move in a horizontal direction and from sliding front or back and side to side.It is more important in lower complete denture.If the ridge is higher and broader than there will be better stability. Iida Y. AAThis investigation was carried out to analyze the physical factors of saliva affecting denture retention. If extension of denture is too far in the sulcus than the muscular activity can cause displacement of denture along with sulcus ulceration. Following this the tooth doctor must use the patient to get success in issues such as speech, mastication, esthetics and neuromascular control. The individual is guided to use the tongue, cheek and lip muscles for denture retention. Introduction Definition Factors affecting retention - Classification - Interfacial force - Adhesion -Cohesion -Oral & facial musculature 2. drchetan. Complete denture success for patients and dental practitioners(2003). The vaccum is created by applying pull which boost the volume level between denture foundation and underlying tissues to keep seal around some area for lower pressure to be constant. Comfortable Dentures Need Support, Steadiness and Retention. Oral Exam Clinical Factors InfluencingStability, Retention, and Support of Complete Dentures 26. When a solid surface is wetted by liquid, its retention raises. The adhesion is more if contact viewpoint is less. The retention of complete dentures 401 achieved through ionic forces between charged salivary glycoproteins and surface epithelium or acrylic resin. Escoe R. Psychomotor patient training to enhance retention of complete dentures. Adhesion is the physical connection between two unlike substances with each other. In pshycomotor patient retention of denture is a difficulty which is resolved by proper counselling of patient. " 1989, The Journal of Prosthetic Dentistry. The upper denture is extended as far as possible however, not on the gentle palate. If the flange of denture is slim and the cells is at snooze, the saliva moves rapidly between the tissue areas, flange and then to the fitting surfaces will cause the easy displacement of denture. Minakuchi S(1), Takaoka S, Ito J, Shimoyama K, Uematsu H. Author information: (1)Department of Gerodontology, Graduate School, Tokyo Medical and Dental University. The ongoing use of denture in diabetic patient may loss retention anticipated to bone resorbtion. Factors Affecting the Selection . How to overcome common difficulties(in brief). For edentulous patients, successful denture therapy is influenced by the biomechanical phenomena of support, stability, and retention. The disruption of this may lead to loss of retention. Retention also will depend on the scale and quality of denture bearing area. Definitions – Removable Prosthodontics Retention – Resistance to vertical displacement of the denture away from the denture bearing surface during. FActOrs AFFEctING rEtENtION IN FIXED PArtIAL DENtUrEs 1. The continuous use of denture in diabetic patient may loss retention due to bone resorbtion.Thus relining or rebasing of denture is required to increase retention.In pshycomotor patient retention of denture is a problem which is solved by proper counselling of patient.” A training device is made in combination with an exercise program to teach muscle control for retention of a mandibular denture. After the inserting denture in mouth, a pressure or drive is put on get retention. Th… Research Article. The flatter the palate, difficult to replace the denture as compared to high palate. The patient is then instructed to displace the seated record base by pulling on the scale. 3. Stability is the protection for denture base to move in a horizontal course and from sliding front or back and side to side. -Atmospheric Pressure -Undercuts, Rotational insertion paths, Parallel walls -Gravity Denture … "(B. W. Darvell, and R. K. F. Clark. In denture it is mainly applicable on the list of saliva and the denture basic material(acrylic resin). In spite of the increasing use of dental implants, the most common way to treat edentulousness is still by means of a conventional full denture. The whole treatment in the fabrication of complete denture including problems in retention, support and balance of denture must be explained to the patient. The keeping artifical teeth and arch form should me maintain in the same postion as that of natural tooth in order that they will work in a tranquility with musculature. http://www.drchetan.com/wp-content/uploads/2010/04/maxilla-mandible-denture-bearing-area.png, Dr. Chetan ;Objectives of Impression making in complete denture; 2010. the tongue and surrounding musculature without which it impossible to achieve proper retention and stability of the complete denture. Under normal conditions as there is no pressure difference and no static retaining force so the atmospheric pressure has no bearing on retention. Factors Affecting Retention Of Denture Health And Social Care Essay. There are several forces that try to displace the denture away from the path of insertion. http://www. Support is the ability of denture to move vertically towards the arch.It is provided by gums and buccal vestibule in mandibular arch while in maxillary arch palate helps to support denture.In order to get good support denture flanges should be larger. (B. W. Darvell, and R. K. F. Clark). In order to get balance occlusion the maximum number of tooth should be in contact with eachother. The whole treatment in the fabrication of complete denture including problems in retention, support and balance of denture must be explained to the patient. CONTENTS:- Introduction Definition Factors affecting retention Conclusion 3. Mucosa borne complete denture is the conventional treatment modality adopted most commonly for the edentulous patients. “Thus, all parts of the system of denture and wearer are exposed to the atmospheric pressure, and the hydraulic nature of the soft tissue means that, under ‘resting’ conditions this will be transmitted into the region between denture and tissue hydrostatically”. Following this the tooth doctor must use the patient to get success in issues such as speech, mastication, esthetics and neuromascular control. Part II: stability J Prosthet Dent. By clicking “Proceed”, you agree to our terms of service and privacy policy. A training device is made in combination with a fitness program to instruct muscle control for retention of an mandibular denture. This study investigated the prevalence and the factors affecting the use of denture adhesives (DA) by older complete denture wearers. This must also be achieved at the expense of some displacement of the supporting soft tissue, and if this created a better fit, it would not last long as that tissue rebounded elastically”. It is the difficulty to seprate two well adapted surface having slender film of liquid between floors which is due cohesive forces take place at surface of water. It is only workable when there is lower pressure under the denture and occurrence of vaccum. Retention is an important parameter in the success of the prosthodontic treatment.
