“…This may be due to unfavourable bone quality, morphology or volume in the proposed fi xture sites. 28 There was a small cohort of patients that were planned for signifi cant oral/ maxillofacial surgical procedures, eg osteotomies, ridge augmentation and sinus lifts, as a prerequisite to their implant treatment.…”

“…These options include accepting the space, orthodontic space closure with substitution of the lateral incisor by the canine, or opening the space for tooth replacement. [5][6][7][8][9][10] Currently, osseointegrated implants are the preferred treatment alternative by many den tists for replacing missing anterior teeth. 10 Many patients with congenitally missing maxillary lateral incisors lack sufficient space for ideal restoration.…”

The influence of varying maxillary lateral incisor dimensions on perceived smile aesthetics

et al. 2007

• The results of this study suggest that the 'golden proportion' should not be a single value but rather a range.• Hypodontia patients showed a preference to a longer lateral incisor as compared to the other groups.• What is aesthetically pleasing to the clinician and patient may not be the same.• Communication and presentation of all diagnostic information to the patient is essential when undertaking treatment planning. VERIFIABLE CPD PAPERThe influence of varying maxillary lateral incisor dimensions on perceived smile aesthetics Objective The aim of this study was to determine the infl uence of varying the dimensions of the maxillary lateral incisors on perceived smile aesthetics. Design Clinical study. Setting Postgraduate dental teaching hospital. Methods A photograph of a female smile displaying only the lips and teeth was digitally altered. First, the width of the maxillary lateral inci sors, in proportion to the central incisor, was altered at 5% intervals to produce six images (52%, 57%, 62% [the 'golden proportion'], 67%, 72% and 77%). In a second group, the length of the lateral incisor was altered at 0.5 mm increments to produce five images with the lateral incisor 0.5 mm, 1 mm, 1.5 mm, 2 mm and 2.5 mm shorter than the adjacent central incisor. The photos were ranked from 'most attrac tive' to 'least attractive' by 41 hypodontia patients, 46 non-hypodontia 'control' patients and 30 dentists. Results: The 67% followed by the 72% lateral-to-central width proportions were the 'most preferred' by all groups. A maxillary lateral incisor that is 1-1.5 mm shorter than the central incisor was the 'most popular' maxillary lateral incisor length. The very short and very long maxillary lateral incisor was consistently perceived as 'least attractive'. Conclusion There is no evidence to suggest that the golden propor tion should be considered the ideal aesthetic standard when creating space for the replacement of missing lateral incisors.

“…4,6 There are several treatment options for managing missing lateral incisors. These can vary from no treatment at all and accepting a space, 7,8 to orthodontically closing a space, [9][10][11][12][13] or orthodontically opening, maintaining or redistributing a tooth space in preparation for its prosthetic replacement. [14][15][16][17] The treatment that is provided can involve multiple dental specialties and is dependent on a number of issues.…”

Objective To analyse the clinical performance and factors influencing the survival of resin-bonded bridgework provided for hypodontia patients with missing maxillary lateral incisors, following orthodontic treatment to open, maintain or redistribute the missing tooth space. Design A retrospective analysis of patients treated at a single centre using case notes with all patients invited for review to corroborate findings. Setting Departments of Orthodontics, Child Dental Health and Restorative Dentistry, Newcastle upon Tyne Dental Hospital and School. Subjects and methods Between 1989Between -2000 suitable hypodontia patients were identified of whom 45 had complete records. For these patients 73 resin-bonded bridges (RBBs) were provided. Following invitation, 24 patients attended for a review appointment. The survival of the RBBs, grade of operator providing treatment, duration of postorthodontic retention, the influence of design, presence of pontic contact in static and dynamic excursions, and the effect of habits were assessed. Life table, Kaplan-Meier and Cox regression analysis were carried out for the 73 RBBs with complete records. A separate analysis of the RBBs provided for patients who attended for the invited review did not show a higher failure rate than those patients who did not attend. Therefore both sets of data were combined. Results Of the 73 RBBs provided, 30 had debonded on at least one occasion (41.1%), six of these debonds were due to trauma (20%). The mean survival time of all the restorations was 59.3 months, with a median survival time of 59 months. Senior members of staff (Consultant, Senior Lecturer or Specialist Trainee) provided most restorations (n = 39) and achieved the highest mean survival of 72.6 months and median
