Growth Indicator

Facial growth indicator line was originally developed by Dr John RC Mew. Dr Mew discloses a facial growth indicator in his textbook, Bioblock Therapy published in Great Britain by Dr Mew. The indicator line—this is defined as the distance from the tip of the nose to the incisal edge of the lowest upper central incisor. Andy’s facial growth indicator is a modification of facial growth indicator, which was originally developed by Dr Mew.

ABSTRACT Purpose To determine the functional position of labial, lingual and buccal frenii with the corresponding central incisor, premolar or molars in natural dentition. Materials and method 20 dentate subjects between 20-40years of age were selected for the study. Maxillary and mandibular impressions were made and the distance from anterior attachment of frenum to the cusp tip of the corresponding tooth was measured. Result The mean distance between the anterior attachment of labial frenum to the incisal edge of incisor was 12.25mm, the mean distance between the anterior attachment of buccal frenum of right side to cusp tip of corresponding teeth was 12.75mm and left side was 12.8mm and the mean distance between the anterior attachment of lingual frenum to incisal edge of incisor was 15.4mm. The coefficient of variation were 14.7%, 16.65%, 15.75% and 6.4% respectively. Conclusion The distance between the anterior attachment of the frenum to the cusp tips/incisal edges can be used as a pre-extraction record for determining the original vertical position of teeth.

Purpose:  To evaluate the reliability of the visibility of the central incisor & the canine for the cervico incisal positioning of anterior maxillary teeth related to age & sex while the upper lip was in repose in dentate patients & the development of rehabilitation recommendations for edentulous individuals with regard to the location of the maxillary incisal edge Methodology: 308 subjects [152 Males & 156 Females] belonging to the age of 30 to 59 years were selected using a simple stratified random technique. There were three age and sex groups: Group I was 30 to 39 years old, Group II was 40 to 49 years old, and Group III was 50 to 59 years old. The vertical distances (in mm) between the lower border of the upper lip and the right maxillary central incisal edge and canine tip were measured and recorded using adhesive tape marked with millimetres. A single examiner recorded all the measurements and the values were tabulated and subjected to statistical analysis. Results: Men in Groups I and II had maxillary central incisor exposure ranging from +6 to -1mm, whereas males in Group III had exposure ranging from +5 to -2mm. There was an exposure range of +6 to -2 mm in females in Group I, +7 to -2 mm in Group II, and +5 to -2 mm in Group III for the central incisors. While the canine exposure in Group I and II and Group III ranged from +2 to -4mm in females, the exposure ranged from +3 to -3mm in men of all ages. In all groups, females had statistically significant (P0.05) more central incisor and canine exposure than men. Conclusions: The canine visibility was less variable in all the age groups and in both males and females in comparison to the central incisor. When restoring edentulous individuals, the average canine exposure dimension can be employed for cervico-incisal location of the anterior maxillary teeth.

He had no history of trauma in that area but the tooth was discolored gradually (Figure 1A). Furthermore, the tooth was asymptomatic. There was no pain and discomfort during mastication. The patient had gastric irritation for the last 5 years and still using omeprazole irregularly. The clinical examination indicates that the left central incisor tooth was yellowish in color and the dentine was found to be exposed (Figure 1B). There was gross tooth tissue loss at the labial surface that includes the incisal edge of the tooth.</p>

ABSTRACT Objective: To investigate the influence of incisal edge asymmetry of the maxillary central incisors on dentofacial esthetics among orthodontists, prosthodontists, and laypersons using video analysis. Materials and Methods: Full-face films of a 52-year-old afro-descendant woman displaying various levels of incisal wear in the esthetic zone were captured. An acrylic resin mockup was made of the maxillary anterior region, enabling the reproduction of an attractive smile and restoring tooth wear. Four different levels of incisal asymmetry between the upper central incisors in 0.5 mm increments were prepared from this mockup. A film was made for each level of asymmetry (0.5, 1.0, 1.5, and 2.0) and one with no asymmetry, with the patient repeating a sentence, totaling five films. After a pilot study and sample calculation, the films were evaluated by 138 examiners: 46 orthodontists, 46 laypeople, and 46 prosthodontists. Each examiner evaluated the dentofacial esthetics of each film using visual analog scales. Data collected were statistically analyzed. Results: Highest scores were awarded to the film with no asymmetry between upper centrals and the one with 0.5 mm of asymmetry. The asymmetries of 1.5 mm and 2.0 mm had the lowest scores from all three groups. Conclusions: The results of this video analysis indicate that asymmetries equal to or greater than 1.0 mm between the upper central incisors edges jeopardize dentofacial esthetics.

Gummy Smile

Objective: This study aimed to compare the changes in the gummy smile in cases treated with botulinum toxin (BTX) application or orthognathic surgery. Methods: The retrospective sample comprised 61 subjects with gummy smile divided into 2 groups according to treatment received for gummy smile correction: 1-38 patients (6 male; 32 female), at a mean age of 28.60 years (s.d.=6.09), treated with BTX application; 2- 23 patients (7 males and 16 females) at a mean age of 29.59 years (s.d.=5.72) treated with orthognathic surgery. Patients from the BTX group refused to undergo orthognathic surgery. The measurement of the gingival exposure was performed in extraoral photographs of the posed smile, before and after treatment, and it was defined as the difference between the stomion of the upper lip and the incisal edge of the maxillary central incisor minus the height of maxillary central incisor obtained in the patient's dental casts. The data were obtained before (T1) and after treatment (T2) and change of gingival exposure with treatment (T2-T1). Intergroup comparison of gummy smile was performed with independent t-tests. Results: The surgical group presented significantly greater correction of the gummy smile with treatment than the BTX group. Conclusion: Gummy smile presented a greater improvement in patients treated with orthognathic surgery than with botulinum toxin application.

ABSTRACT Aim To verify the influence of different bracket shapes and placement references according to Andrews and MBT systems on the expression of angulation in upper central incisors (UCI). Materials and methods Bracket positioning and mesiodistal dental movement simulations were performed and the angulations produced in the dental crown were evaluated, based on computed tomography scan images of 30 UCI and AutoCAD software analysis. Rectangular (Andrews) and rhomboid (MBT) brackets were placed according to the references recommended by Andrews and MBT systems – long axis of the clinical crown (LACC) and incisal edge (IE) respectively. Results Data showed that the use of LACC as reference for bracket positioning produced 5° and 4° UCI angulations in Andrews and MBT brackets respectively. The use of IE produced a 1.2° mean angulation in UCI for both brackets. Conclusion When the LACC was used as reference for bracket positioning, the UCI crown angulation corresponded to the angulation built into the brackets, regardless of shape, while the use of IE resulted in natural crown angulation, regardless of bracket shape. Clinical significance This research contributes to guide the orthodontist in relation to the different treatment techniques based on the use of preadjusted brackets.
