A retrospective cohort study on dental implant survival in patients with grafted alveolar clefts.

OBJECTIVES: The aim of this study was to assess the survival rate of dental implants inserted in an alveolar cleft area where one or more bone graft procedures were performed and to identify possible factors that affect the survival rate. MATERIALS AND METHODS: The available data from 78 implants placed in 64 patients with grafted alveolar clefts were retrospectively analysed. Statistical analyses were performed using Kaplan-Meier survival analysis, log-rank tests and univariable Cox proportional hazard models. RESULTS: The median follow-up period from insertion to the last follow-up appointment was 46 months (IQR: 29-79.3). In five patients, a single implant failed. This resulted in a cumulative survival rate of 95.0% at median follow-up. The factors investigated in this study did not have a significant effect on implant survival. CONCLUSIONS: Dental implants placed in patients with alveolar clefts are a reliable treatment option for dental rehabilitation.

Orofacial abnormalities in mucopolysaccharidosis and mucolipidosis type II and III: A systematic review.

Mucopolysaccharidoses (MPSs) and mucolipidosis II and III (ML II and III) often manifest with orofacial (progressive) abnormalities, which may have a major impact on quality of life. However, because these patients have multiple somatic health issues, orofacial problems are easily overlooked in clinical practice and available literature on this topic solely consists of case reports, small case series, and small cohort studies. The aim of this systematic review was to gain more insight in the nature and extent of orofacial abnormalities in MPS, ML II, and III. A systematic review of all previously published articles addressing orofacial abnormalities in MPS, ML II, and III was performed. Both clinical studies and case reports were included. Outcome was the described orofacial abnormalities, subdivided into abnormalities of the face, maxilla, mandible, soft tissues, teeth, and occlusion. The search resulted in 57 articles, describing orofacial features in 340 patients. Orofacial abnormalities were present in all subtypes of MPS, ML II, and III, and consisted of thickened lips, a hypoplastic midface, a high-arched palate, hypoplastic condyles, coronoid hyperplasia, macroglossia, gingival hyperplasia, thick dental follicles, dentigerous cysts, misshapen teeth, enamel defects, and open bite. Orofacial abnormalities are present in all subtypes of MPS, ML II, and III. As orofacial abnormalities may cause complaints, evaluation of orofacial health should be part of routine clinical care.

Is masticatory performance affected after a unilateral condylar fracture? A cross-sectional study.

BACKGROUND: Mandibular fractures, especially condylar fractures, are one of the most common facial fractures. Trauma to this region could possibly compromise masticatory performance, which is a vital function for humans. OBJECTIVE: To objectively determine masticatory performance (Mixing Ability Test; MAT) in patients treated for a unilateral condylar fracture, thereby comparing patients in open and closed treatment groups, and assessing whether there is a positive relationship between this performance and subjective mandibular function (Mandibular Functional Impairment Questionnaire; MFIQ). METHODS: Fifty-eight patients were enrolled in a cross-sectional study and examined on an additional appointment at least 1 year after trauma, during which the patients performed the MAT and completed the MFIQ. The Spearman test was used to assess the correlation between the Mixing Ability Index (MAI) and the MFIQ score. A linear regression was used to explore the effects of different factors on the MAI. RESULTS: The correlation between objective masticatory performance and the subjective mandibular function was positive (r = 0.250; P = 0.033). Better masticatory performance was observed in patients who were male, received physiotherapy, had no other mandibular fractures and/or had satisfactory self-perceived occlusion. No significant difference in the MAI was found between the open and closed treatment groups. CONCLUSION: Independent of the chosen treatment, at least 1 year after treatment, individuals who experienced a unilateral fracture of the mandibular condyle exhibit masticatory capacity comparable with that of individuals who have not suffered such injuries.
