Establishment of integral biomechanical balance in the correction of tongue source skeletal dentomaxillofacial open bite deformities.

The objective of this clinical paper is to demonstrate an effective process to achieve relative long-term functional and aesthetic stability after the treatment of skeletal tongue source open bites. This therapy consisted of applying Delaire's architectural analysis as the cephalometry to make treatment plan corresponding to the patients' own craniomaxillofacial integral architectural structure to achieve the optimal skeletal anteroposterior and vertical position. In addition, glossoplasty and transverse matching of upper and lower arches must be under consideration in the goal of achieving integral biomechanical functional balance and aesthetic harmony. Little relapse of both skeleton and occlusion was found more than 3 years posttreatment. The effect of pararthria correction coursed by lingual functional impediment is also attained.

[Oral health status of patients undergoing hemodialysis: a Meta-analysis].

OBJECTIVE: This study aimed to systematically evaluate the oral health status of patients suffering from chronic renal failure and undergoing hemodialysis (HD). METHODS: Electronic databases, namely, China National Knowledge Infrastructure, Wanfang Data base, PubMed, Web of Science, and Cochrane Library, were searched until May 2016 for cross-sectional and case-control studies that investigated the oral health status of patients suffering from chronic renal failure and undergoing HD. Two reviewers independently screened the trials, extracted the data, assessed the quality, and conducted a Meta-analysis with RevMan 5.3 in accordance with the inclusion and exclusion criteria. RESULTS: Sixteen studies satisfied the eligibility criteria. Meta-analysis revealed that plaque index (MD=0.62, 95%CI: 0.51-0.72), calculus index (MD=1.09, 95%CI: 0.56-1.63), probing depth (MD=0.63, 95%CI: 0.29-0.98), and attachment loss (MD=0.63, 95%CI: 0.56-0.69) were significantly higher in the patients undergoing HD than in the healthy control group (P<0.01). No significant differences in decayed missing filled teeth (MD=1.12, 95%CI: -1.08-3.32) were observed between the patients undergoing HD and the healthy control group (P=0.32). CONCLUSIONS: The prevalence of caries in patients undergoing HD is similar to that in the healthy control group. However, these patients are at a higher risk of acquiring periodontal diseases than the healthy control group. Thus, the oral health status of these patients should be further evaluated in clinical treatments.
