measurements,the non-contact 3-dimensional(3D)digitiser and the analytical software were used for 21 patients withdefects classified into Class I or II of the Aramany classification. Results:It was quantitatively demonstrated thatfacial deformities resulting from partial maxillectomy were due to concavities from the subnasal point to thementolabial groove in the vertical range,and from the region around the nasal alar to the anterior cheek in thelateral range.Facial features anterolaterally expanded on the defected side in volume with the prosthesis.Facialdisfigurement extended to the lower face,and improvement of these deformities was also observed with theprosthesis.Using the non-contact 3D digitiser,the direction and amount of movement of the facial componentswithin the mid-and the lower face regions were 3-dimensionally determined,enabling rapid and accurate identificationof facial deformities,and recovery of the facial morphology with prosthesis. Conclusion:This is the first studyto analyse of prosthesis-induced changes in facial morphology after partial maxillectomy with a non-contact 3D digitiser.
