factors affecting retention of complete denture

It is the difficulty to seprate two well adapted surface having thin film of liquid between surfaces which is due cohesive forces occur at surface of liquid.It is same to the forces which causes the liquid to rise in capillary tube. (B. W. Darvell, and R. K. F. Clark). 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. Antolion C, Kotwal K, Mangelsdorff D. Analysis of posterior palatal seal and the palatal form as related to the retention of complete dentures. The placement of artifical teeth and arch form should me maintain in the same postion as that of natural teeth so that they will work in a harmony with musculature.The teeth is then better to place in a neutral zone.In order to get balance occlusion the maximum number of teeth should be in contact with eachother.After the insertion of denture,high occlusal spots should be removed to enhance the efficacy and retention of denture. A complete denture (also known as a full denture, false teeth or plate) is a removable appliance used when all teeth within a jaw have been lost and need to be prosthetically replaced.In contrast to a partial denture, a complete denture is constructed when there are no more teeth left in an arch, hence it is an exclusively … Any opinions, findings, conclusions or recommendations expressed in this material are those of the authors and do not necessarily reflect the views of NursingAnswers.net.

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. When the denture is dislodged, this space is forced to expand and the meniscus recedes, but the recession is impeded by the viscosity of the saliva and a negative pressure is generated under the denture. 1. Retention of complete dentures 1. 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. 2.

RETENTION IN COMPLETE A most important The functional anatomy of the denture foundation areas of the maxilla and mandible is presented in detail – in particular, the relationship of these anatomic structures that impact retention… •A bilaterally balanced denture occlusion is intended •Stability – resistance to horizontal and rotational forces •The biomechanical phenomena of … These forces are increased when the denture base is close to the mucosal surface.The flatter the palate,difficult to displace the denture as compared to high palate. Factors involved in complete dentures •Retention – resistance to vertical dislodging forces •Complete denture retention is, in part, influenced by denture occlusion. FACTORS AFFECTING RETENTION IN COMPLETE DENTURE 2. DENTURE. If extension of denture is too far in the sulcus than the muscular movement can result in displacement of denture along with sulcus ulceration.If it is less extended into sulcus there is less retained saliva and the loss of retention.The upper denture is extended as far as possible but not on the soft palate.This shows that the posterior seal is not present.It is obtained if the displaced tissue also move with the denture during function.This can be done by making post dam area by creating raised grooves on posterior surface. Clipping is a handy way to collect important slides you want to go back to later. IN COMPLETE DENTURE Specific learning objectives 1. Retention is an important parameter in the success of the prosthodontic treatment. It consists of a shellac record base which is connected with string to an extraoral spring balance scale. 1983 Feb;49(2):165-72. doi: 10.1016/0022-3913(83)90494-8. Adhesion is the physical interaction between two unlike molecules with one another.In denture it is mainly applicable among the saliva and the denture base material(acrylic resin).The closer the surface of denture and saliva,the adhesion is increased.The adhesion is more if contact angle is less.The wetting of saliva is more on oral mucosa than on denture base.thus adhesion also depends upon the viscosity of saliva.The thin layer binds more effectively than thick but ropy saliva may have some advantage especially resisting flow into space between denture base and mucosa,this is negated if the film formed is thick in first place. David M. Roessler. The increase in measurements on the scale show good resistance to displacement of the denture base”. FACTORS AFFECTING * William P. Lace D.D.S ... Role of the surface and volume of palatal relief chambers in retention of maxillary complete dentures. Under normal conditions as there is no pressure difference and no static retaining force so the atmospheric pressure has no bearing on retention. The under cut which is present on one side of the ridge helps in retention but bilateral under should be surgically corrected as they cause difficulty in retention of denture.The use of denure adhesives and pastes also improve the retention of denture.The magnets and suction disc also play an important role in this regard.Now a days,the use of suction disc is prohibited as continuous use of denture with suction disc affect the palate and may result in oroantral communication. The patient is then instructed to displace the seated record base by pulling on the scale.

Looks like you’ve clipped this slide to already. The normal movement of oral and facial musculature can also provide retention,if the denture work in harmony with the muscles.The flanges of upper denture slope outwards and upwards in way that the action of buccinator muscle helps to seat the denture.During incision,forces acting anteriorly on the denture is may tend to tip the denture and posterior border of denture move downwards because posteriorly the base of tongue may respond forces which occur anteriorly on denture.
