Analysis of the phone of complete dentures with varions polished surfaces on USSA digital sonagraph

方法：塑料基托组：塑料基托厚2.0～2.5mm，腭前区磨光面光滑；

METHODS : Plastic base group : the plastic base was 2.0 - 2.5 mm thick , with smooth anterior palate polished surface .

而同种材料间义齿基托组织面、磨光面菌落数则无显著差异（P005）。

However , the significant difference between the tissue surface and polish surface of the same material as base ( P0 05 ) was not discovered .

Take care to avoid to put your fingers on polished surface .

有条痕的磨光面则称为擦痕面。

The striated and polished surfaces are called slicken-sides .

对不同磨光面外形的全口义齿咀嚼效能的测定和分析

Objective : In order to study the phone of complete dentures with various polished surfaces .

碳纤维织布不同位置的加强形式对其强度有影响，位于基托中间层的强度高于近组织面及磨光面者。

The bending strength of denture - base reinforced in the middle layer was higher than reinforced in the tissue face or the polishing face .

但是有40%的患者钛腭托磨光面使用后出现色素沉着，这可能与患者的饮食习惯和口腔卫生以及义齿加工质量有关。

40 % patients found pigmentation on the polished surface of the titanium palatal dentures . This might relate to patients ' diet habit , oral sanitation and quality of dentures .

戴义齿6个月后，对义齿基托的组织面、磨光面进行细菌培养，计算出菌落数（cfu/mL），比较分析其差异性。

After wearing denture for 6 months , to carry out bacteria culture of tissue surface and polish surface of denture base , and to count colony ( cfu / mL ), and to analyze the difference .

结果：甲基丙烯酸脂基托组织面、磨光面菌落数大于钛合金基托，两者具有统计学差异（P<005）。

Results : The number of colony on tissue surface and polish surface of methyl methacrylate base exceeds the number of colony on tissue surface and polish surface of titanium alloy base , and the significant difference was discovered between the two materials ( P < 0 05 ) .

磨光牙面后，用扫描电镜观察。结果：未洁治牙齿表面有呈纤维状或块状的牙垢和牙菌斑，洁治后未抛光牙面粗糙不平或有划痕缺损。

Results : After ultrasonic scaling without polishing , the teeth were rough and there were nicks , fibers or sheet plaques left on the surfaces before polishing .

高度磨光的金属面象镜子一样反光。

本文的主要工作分为以下几个部分：在第三章中，针对当前大多数磨光方法最多只能磨光三面角的情形，提出了G~1磨光凸n（n≥3）面角的方法。

The thesis is organized as follows : In chapter 3 , we present methods to blend arbitrary convex n & hedral ( n ≥ 3 ) angle with G ~ 1 continuity considering that most blending methods can only blend trihedral angle . Two methods are proposed .
