statement of the problem: implant-retained overdenture can improve the stability of dentures and prevent bone loss. overdenture-wearing patients need special hygiene care. purpose: the aim of this study was to evaluate the effects of various denture cleansers on the retention of dio orange o-rings. method and materials : in this experimental study, 40 dio orange o-rings were divided into 4 grou...

Patients wearing conventional dentures often complain about the instability of the prosthesis, particularly the mandibular denture. Denture instability leads to feeling of insecurity, inefficient mastication, and overall dissatisfaction with the prosthesis. Implant-retained dentures have been developed and studied as a method for solving the problem of instability associated with conventional d...

Purpose. Nowadays, the advancements in direct metal laser sintering (DMLS) technology allow the fabrication of titanium dental implants. The aim of this study was to evaluate implant survival, complications, and peri-implant marginal bone loss of DMLS implants used to support bar-retained maxillary overdentures. Materials and Methods. Over a 2-year period, 120 implants were placed in the maxill...

The retention of a complete denture and the patient’s adaptation varies considerably among different individuals. Resorption of the edentulous alveolar ridge differs greatly and some patients need implant-retained overdentures to enable adequate retention of their prostheses. In some extreme cases it is necessary to increase the volume of the alveolar ridge with bone grafts. The aim of this stu...

Partially edentulous patients with missing premolars and molars have been conventionally rehabilitated using the free-end removable partial dentures (RPDs). With the advancements in implant dentistry, the benefits of implant-retained/supported mandibular implant overdentures relative to conventional mandibular dentures with bilateral extensions (Class I Kennedy) have now been extensively invest...

Aim: To compare the chewing process and swallowing threshold parameters of subjects with complete dentures and overdentures with data obtained from subjects with complete natural dentitions. Methodology: The chewing process in terms of swallowing threshold parameters of four groups of subjects with complete dentures (all females) was quantified by sieving particles after chewing of an artificia...

AIM: The aim of the study was to assess difference between patient satisfaction and bone height changes mini-implant supported overdentures in comparison with conventional implant after expansion technique. METHODS: This randomized clinical trial contains 36 edentulous participants thin mandibular ridges randomly divided receive 2 mini-implants, or implants ridge splitting, both treatments were...
