Background An impotant step in maintaining smile to replace missing teeth. When teeth are missing, the remaining ones can change position, drifting the surruonding space. Teeth that are out of position can damage tissues in the mouth. A denture helps you properly chew food, a diffi cult task when you are missing teeth. In addition, a denture may improve speech and prevent sagging face by providing support for lips and cheeks. A partial denture is suitable for those who have some natural teeth remaining.While missing one and two adjacent teeth can often be best restored fi xed bridge or implant, partail denture work best to replace multiple missing teeth. Removable partial denture usually consist of replacement teeth attached to pink or gum- colored plastic bases, which are connected by framework. Removable patial dentures attach to your natural teeth with metal clasp or devices called precision attachment. Precision attachments are generally more estetic and cost more than those metal clasps. Denture with metal and wrought wire clasps are generally more fi t and stay in place much better than (provisional) denture. Objective The main purpose of this study is to develop of provisional denture. Materials and Methods This study has been used to study medicine. Enerel dental clinic served 1481 people whom they were made denture between 2003 and 2005. from those people were made denture with wrought clasp for 60 people. By experimental study, jawing activity test has been used by I.S.Rubinov method. Results Denture with wrought clasp needs was increasing gradually until 56 percents in 2003, 82.1 percents in 2004, 93 percents in 2005. A large number of denture with wrought clasp was made 32.4 percent of maxilla, 47.1 percent was mandible but this denture were used and suited for people 78 percent, 22 percent of people who made those type of denture did not and uncomfortable for them. Denture with wrought clasp jawing activity was 1.920.13 seconds and jawed things weight was1.89 0.1, lost of jawing activity was 2.691.44 (=0.001). Conclusion Method of denture with wrought clasp is simpler and nearly minted removable denture.

The age of 12 permanent molars 6 source formation, teeth grow footnote rows of teeth to catch various dental routine dental transferred under the grip. Operations and development perspective 6th gear teeth with dental row a key role to ensure a balance between teeth. This is the dental caries and other reasons deviations in adjacent teeth, jaw bones flaw, merge lengthen teeth, chewing on a toothpick footnote central line switch the arc fault is the key basic conditions.We study in MNUMS Dental school 2013-2014 customers in 1:1 ratio unfolded taken x-ray studied biological life in a sample of pictures of children over the age of 12 . Picture Image J 1.49b measurement statistics into the application development with SPSS 17.0.Biological age of 12 years old 6th gear teeth grow reach during our study involved 56 children , 18 ( 32.14 %) were taken in 6th gear teeth .Therefore, the 6th gear to be controlled from the start grow regular dental caries prevention laces jaw bone and teeth abnormalities shows the importance of the development.

Learning objectives: After reading this article, readers should be able to:1. Get information about brief historical aspects of the cleft palate treatment;2. Understand techniques used to repair various types of the cleft palate;3. Understand the optimal timing of the cleft palate repair;4. Understand the results and complications following palate repair including speech, maxillary growth, and fistula formation, regarding with operative techniques and timing of palatoplasty.Summary: Cleft palate is more common congenital anomaly, but surgeons have been eluding surgical correction of the cleft palate for centuries. Many surgical techniques have been described during last two centuries, the goals of these include separating the nasal and oral cavities (avoiding fistulas), establishing normal speech, and preserving maxillofacial growth. This article reviews the brief historical aspects of the cleft palate, palatoplasty techniques, the optimal timing, and the results and complication associated with palate repair technique and timing.

BACKGROUND. The measurement of oral health is recognized as a critical feature of numerous dental activities: describing normal biologic processes, understanding the natural history of disease, testing hypotheses regarding preventive agents, and planning and evaluation of health services. In modern times, statistical methods are widely being used to describe the probability of caries formation by calculating the progress and progression of dental caries for each individual by means of investigational correlations to detect and control risk factors for dental caries and periodontal diseases. OBJECTIVE. The purpose of this study is to identify the correlation between the incidences of dental caries (DMFT) and its influencing risk factors for Mongolians in order to establish the fundamental criteria for oral health index. MATERIAL AND METHODS. Data were collected from 240 volunteers in six different age groups by using a questionnaire and an intra oral examination combined with laboratory tests. The oral health index is divided into 5 major categorical factors including the residual number of natural tooth, caries state, periodontal state, other oral health state and oral health management habits and systemic condition that determines the relationship between the incidences of dental caries and influencing risk factor for each item. RESULTS. Significantly different results were observed for Mongolian people in terms of prevalence and proportion of oral disease and oral state which led to the establishment of criteria for oral health index by statistical significance factors in all age groups (p <0.05). CONCLUSION. It is possible to create and introduce a scoring system of individual oral health index that could be applied to the evaluation oral health program that is suitable for calculating future illnesses and prognosis of oral diseases.
