全口义齿是一种传统的修复方式,因口内无牙,义齿的固位困难,牙槽嵴低平患者的义齿固位更加困难;低平的牙槽嵴表面的黏膜薄,很容易产生压痛.固位不良、咬合疼痛就无法发挥咀嚼功能,更谈不上美观,这些问题一直是牙槽嵴低平患者全口义齿修复的难点.近年来从固位原理、临床制作技术、义齿粘附制剂、基托软衬材料、种植技术等方面都有了一定的进步.     

软衬材料改善慢性下颌牙槽嵴疼痛的临床评价

下颌骨全牙列缺失会导致下牙槽嵴的吸收,部分患者由于牙槽嵴重度吸收,黏膜变薄松弛。在总义齿修复时,出现普通调改无法缓解的疼痛,此时使用软衬材料重衬组织面是解决此类问题的一个重要方法。     

牙槽嵴形态对全口义齿重衬效果的影响

影响白色念珠菌在义齿软衬表面粘附的因素

义齿软衬材料适用于牙槽嵴萎缩的全口义齿修复患者.但在使用过程中,不可避免地会产生真菌在其表面粘附现象.真菌在义齿软衬材料表面大量黏附,一方面可以导致义齿性口炎的发生,另一方面也会加速材料的老化,影响其使用.本文从软衬材料及口腔环境两个方面,就影响白色念珠菌在义齿软衬表面粘附的因素作一综述.

Dimensional changes of relined denture bases with heat-cured, microwave-activated, autopolymerizing, and visible light-cured resins. A laboratory study

The dimensional changes of relined denture bases were evaluated in a laboratory study. Heat-cured resin, two autopolymerizing resins, microwave-activated resin and a new visible light-cured resin were used as relining materials in this study. The gaps between the metal die and the relined denture bases were measured immediately after the relining procedure and subsequently on the first day, first week, fourth week, and eighth week. The relined denture bases were stored in distilled water at 37°C between measurements.
It was shown that dimensional changes in relined denture bases were influenced by the relining materials and procedures, and that heat-cured resin proved to have the smallest dimensional change as well as the greatest dimensional stability in comparison with the other relining materials and procedures.

Changes in the masticatory function of complete denture wearers after relining the mandibular denture with a soft denture liner

PURPOSE: The purpose of this study was to examine changes in the masticatory function of complete denture wearers after relining the mandibular denture with a soft liner. MATERIALS AND METHODS: Conventional complete dentures were fabricated for 6 completely edentulous patients. One month after completing adjustments of the dentures, maximum biting force, masticatory performance, and electromyography of the masseter muscle during mastication were recorded. Chewing strokes, chewing time, muscular activity, and masticatory rhythm were calculated using the recorded electromyography. The mandibular dentures were then relined with a soft liner. One month after finishing adjustments of the relined dentures, the same tests were performed. These values were compared using a paired t test (alpha = 0.05). RESULTS: When using the soft liner, masticatory performance and maximum biting force were significantly greater (P = 0.019 and P = 0.023, respectively). In addition, the number of chewing strokes was significantly lower (P = 0.020), and chewing time was reduced (P = 0.010). A more stable masticatory rhythm was also found in the initial chewing stage. The muscular activity tended to decrease after the insertion of the lined denture, but no significant difference was found between before and after relining. CONCLUSION: It was shown that applying a soft lining material to the mandibular dentures of 6 edentulous patients improved masticatory function with no adverse effect on the muscular task.

全口离齿固位与适合度对咀嚼效能的影响

影响全口义齿的因素很多，其中义齿的固位和适合度对其的行使有密切的关系，本文采用软性衬垫材料，对２２名戴用全口义齿后因固位不良，疼痛等以致咀嚼效能下降者进行加衬治疗，并在治疗前后，采用吸光度法进行咀嚼效能的测定比较。结果表明全口义齿的固位和适合度与咀嚼效能关系密切。加衬光后的全口义齿，由于固位改善，适合度提高，其咀嚼效能立即有了明显改善，治疗后的咀嚼效能平均是治疗前的２０９％。接受治疗的病例中。９０     

Clinical evaluation of a chemically cured hard denture relining material

The purpose of the current study was to evaluate the clinical performance of a chemically cured denture relining material after 1-year service period. A powder–liquid material designed for denture base relining (Tokuso Rebase Normal-set, Tokuyama Corp., Tokyo, Japan.) was assessed. Fifty adult patients, who required denture reline treatment, participated in the current project. Adaptation of each denture was examined with a silicone elastomeric material, and the surface to be relined was reduced by means of a rotary cutting instrument, then conditioned with dichloromethane. The relining material was spatulated, poured into the relining area, inserted and adjusted after setting. Each relined denture was subjected to base line evaluation immediately after relining and end evaluation after 1 year. Standardized criteria were used for direct evaluation of the material. After an observation period of 1 year, the rate of the relining cases considered to be in clinically ideal condition (Alfa) was 90% for staining, 90% for discoloration, 94% for peeling, 96% for adaptation and 100% for irritation to oral tissue. Only one case was judged as clinically unacceptable (Charlie), and this was for staining. On the basis of a 1-year observation, the Tokuso Rebase material is considered to be a clinically reliable hard denture relining agent.     

Dimensional changes of processed denture bases after relining with three resins.

This study compared the dimensional change of simulated processed denture bases after relining with three resins. Thirty simulated denture bases 1.5 to 2 mm thick were processed from Lucitone 199 resin following the manufacturer's instructions using the long-cure method. Ten bases were relined with Lucitone 199 (long-cure), 10 were relined with Triad resin, and 10 were relined with Accelar 20 resin. The relined bases were processed on a metal die using a reline jig, and three measurements (from distobuccal flange to distobuccal flange) were made with a traveling microscope immediately before and after relining. Each relined simulated denture base showed a significant dimensional shrinkage after processing. The mean dimensional change values of the Triad resin relined bases were significantly greater than those of the other two resin relined bases. All of the dimensional change values, however, would probably be insignificant in a clinical situation.
