Fabrication of a nose prosthesis by means of selective laser sintering and wax powder / 实用口腔医学杂志

ABSTRACT

Objective:To reconstruct a 3-D wax nose model and make a s ilicone elastomer nose prosthesis. Methods:Laser scanning was us ed to get the data of a nose model, selective laser sintering and wax powder wer e used to fabricate a wax nose model,the nose prosthesis was made by silicone el astomer. The differences in length(L),width(W),deepth(D),height(H) and tip-angl e(TA) among the nose models made with plaster, wax powder and silicone elastomer were compared. Results:L(mm) in plaster, wax and silicon e models was 36.61,36.60 and 36.60 respectively.W(mm),D(mm),H(mm) and TA(?) in the three kinds of models were the same:36.23,18.45,43.14 and 74.57 respectively .Conclusion:Nose model made of the wax powder is precise and can meet the requirements for maxillofacial prosthesis.
