RESUMO
Objective To investigate the technical characteristics and clinical feasibility of 2 implant supported immediate loading mandibular implant complete denture by linear occlusion.Methods40 cases of edentulous patients in the fifth people's hospital of yuhang district hangzhou from January 2011 to January 2017 were selected, these patients were divided into 2 implants supported immediate loading implant supported mandibular complete overdenture group (immediate loading implant group, n=20) and conventional complete denture repair group (n=20) two groups according to the treatment methods, the planting denture satisfactions, body marginal bone resorption, complications of the two groups were statistically analyzed.ResultsThe planting retention function, masticatory function, language function, comfort scores of the immediate loading implant group were significantly higher,there was significant difference between two groups(P<0.05), the bone resorption was significantly lower,there was significant difference between two groups(P<0.05), the incidence of complications 10% (2/20) was significantly lower than the conventional complete denture repair group 40% (8/20).there was significant difference between two groups(P<0.05).ConclusionThe clinical feasibility of 2 implant supported immediate loading mandibular implant complete denture by linear occlusion is higher than conventional complete denture repair.
RESUMO
Objective:To study the characteristic of mandibular kinesiography(MKG) of the patients wearing linear occlusal denture or anatomic occlusal denture, and its relation with masticatory function. Methods:The characteristic tracks, range and speed of mastication movement of two groups of patients, 33 wearing linear occlusal dentures and 30 wearing anatomic occlusal dentures, were recorded by MKG and statistically compared.Results:Differences of mandibular movement track in linear occlusal denture group from that of the anatomic occlusion group were found as following:①There was no occlusal contact slide on the frontal plane track. The track of protrusion movement on sagittal plane was a straight line.②The maximum speed of closing of linear occlusal dentures was apparently slower than that of anatomic occlusal dentures (P
