Management of uncorrected cleft lip - an innovative prosthodontic approach

Instancesof uncorrectedc left Up in adult or elderly patients are still seen in rural areas or among the people who are unaware of its correction in the developing countries. Adult patients who did not receive proper treatment for cleft lip are challenging for clinicians in terms of prosthetic rehabilitation especially when the patient become edentulous. This paper presents the management and personal identity revival of a completely edentulous 54 year old patient with uncorrected bilateral cleft lip. The facial deformity was characterized by irregularities of upper lip, protruded and rotated central incisors in the pre-maxillary region with multiple missing teeth in the upper jaw and completely edentulous lower jaw. Complete Dentures were inserted following extraction of the central incisors and the remaining natural teeth in the upper jaw, along with a Lip prosthesis made out of silicone that is retained to the maxillary Complete Denture by means of magnets. The patient was very pleased with the improvement in speech and chewing and she approved of her facial esthetics. The existence of uncorrected cleft in the elderly population highlights the need to improve policies in treating patients with cleft lip, mainly in developing countries

embouchure denture - [a double reed musician's delight]

Wind instrument players are the ones who put their mouth, lips Jaws, teeth, tongue and face to a use which is different from the normal functions of eating, speaking and expression. Hence there is a clear need for an understanding of the dental requirements of players of wind instruments.1 The problems that may arise for the dental surgeon who is treating a wind instrument player are due to the fact that the eligibility of the musical sound produced and how he produces it while playing a musical passage is directly related to muscles of facial expression, during blowing. Hence it is necessary to design a prosthesis that would well adapt to the functional demands of the wind instrumentalist. The purpose of this article is to create an awareness among dental practitioners, about their role in rehabilitating a completely edentulous wind instrumentalist and also describes the technique to fabricate a specially designed prosthesis for wind instrument players -[The Embouchure denture]

In vitro comparative evaluation of the physical and mechanical properties of two soft-liners coated with different types of coatings

Aim: To evaluate the changes on the physical and mechanical properties of acrylic and silicone based soft liners after applying four different types of coatings

Methods: A total of 60 samples were prepared and divided into two major groups viz. Group A-Exact-On [30 samples] and Molloplast-B [30 samples]. Group A and B were further subdivided into 5 subgroups I, II, III, IV and V containing 6 specimens each. The samples were coated with four different types of coatings and were compared to the uncoated control group [subgroupl]. Main composition of two types of Monopoly were chemically activated methylmethacrylate monomer, clear methylmethacrylate polymer, heat activated methylmethacrylate monomer. Two new types of coatings were made with n-butyl cyanoacrylate. These two coatings were never tried before in any literature review. The coated samples were tested for Hardness, Permanent deformation, Tensile strength, Water absorption determination and the coated surfaces were observed under SEM and compared with the uncoated control group

Results: Molloplast-B, a silicone based had longer shelf life but a coated acrylic based liner was seen to be equally good. Cyanoacrylate monomer coating and self cure monopoly coating were superior to other coatings. All results were statistically analyzed by 2-way ANOVA. The mean values for hardness ranged from 24.16 to 29.33 Shore A for Group A and 41.50 to 42 Shore A for Group B. Values of permanent deformation ranged from 1.01 to 0.93% for the Exact-On [Group A] and 0.158 to 0.140% in coated Molloplast-B samples [Group B]. Mean values of Tensile strength ranged from 5kg/cm[2] to 6.00kg/cm[2] in Group A and 16.33 kg/cm[2] to 17.67kg/cm[2] in Group B. It was observed that among the coatings Cyanoacrylate Monopoly coating was more efficient in preventing water absorption and leaching followed by Cyanoacrylate Monomer coating

Conclusion: None of the coatings affected the physical properties of tissue conditioners. All coatings prevented water absorption from tissue conditioner and prolonged the life of tissue conditioner
