Cephalometric appraisal of patients treated with fixed lingual orthodontic appliances: historic review and analysis of cases.

In the first part of this article, a retrospective look was taken of evolvement and progression in design of the lingual fixed orthodontic appliance. The second part is a retrospective study of treated lingual cases. By the use of standardized cephalometric radiographs, selected treatment parameters were analyzed:--namely, bite opening, changes in mandibular position, inclination, torque and intrusion of incisors, and soft-tissue effects. For the clinician who uses this treatment modality, the most significant effects are the bite opening, intrusion of the mandibular incisors (particularly in extraction cases), and limited reduction of lower lip protrusion. The mandibular plane angle and torque and inclination of incisors did not follow a consistent and predictable pattern. On the basis of the study's findings, it is suggested that lingual fixed appliance therapy is a useful supplement to our treatment modalities; good results are both realistic and possible.

Long-term clinical evaluation of toothpaste and oral rinse containing sanguinaria extract in controlling plaque, gingival inflammation, and sulcular bleeding during orthodontic treatment.

A sanguinaria-containing toothpaste and oral rinse regimen was evaluated during a 6-month period to determine its effectiveness in controlling plaque, gingival inflammation, and sulcular bleeding. Oral hygiene instructions and a 1-month prestudy brushing period failed to produce a significant improvement in health among the 24 subjects as determined by the three evaluation parameters. After the oral hygiene period, the subjects were randomly assigned to the active treatment (marketed Viadent toothpaste and oral rinse) or the placebo treatment (same base formulas without sanguinaria). Treatments were evaluated using the Löe and Silness gingival index, the Silness and Löe plaque index, and the Mühlemann and Son sulcular bleeding index at baseline and monthly through 6 months. The sanguinaria regimen reduced plaque by 57%, gingival inflammation by 60%, and sulcular bleeding by 45% from baseline compared with placebo group reductions of 27% (plaque) and 21% (gingival inflammation), and an increase of 30% in bleeding index. Repeated-measures analysis of covariance with baseline scores used as covariates showed statistically significant differences at 6 months for plaque (active 0.39; placebo 0.68, p less than 0.01), gingival inflammation (active 0.32; placebo 0.76, p less than 0.001), and sulcular bleeding (active 0.34; placebo 0.70, p less than 0.002). Results of this study demonstrated that the combined use of the sanguinaria-containing toothpaste and oral rinse controls and reduces plaque and gingival inflammation in an orthodontic population.

Tooth transpositions--a review of the literature and treatment considerations.

This paper defines tooth transposition and discusses its history, incidence and possible etiology. An interesting parallel is drawn between tooth transposition and other dental anomalies (number, size, shape and location of teeth). Treatment options are discussed in terms of the age at which the transposition is discovered, as well as in terms of severity and completeness of the anomaly. While a logical and relatively predictable treatment solution should normally be considered, in some selected cases it may be prudent to venture into more complex treatment solutions.

Bonding characteristics of impacted versus erupted permanent teeth.

Erupted and impacted teeth from young (12 to 24 years of age) and older persons (over 50 years of age) were bonded by a standard technique using etching times of 0, 15, 30, and 60 seconds. Two subgroups of teeth were soaked for 7 days and compared with those in the remainder of the group. Test specimens were loaded in shear to bond failure by means of a testing machine with a 200- kg load cell and a crosshead speed of 5 mm/minute. Results indicated insignificant bond-strength differences between young-impacted and young-erupted teeth for any given etching time. Very small bond-strength differences were found for various etching times (15, 30, and 60 seconds). A significant difference was found between 24-hour soak and 7-day soak for the etching times of 30 and 60 seconds only.

Effect of a mandibular orthopedic repositioning appliance on muscular strength.

Three tests of large-muscle group strength were performed on 14 football players from the University of Louisville. Strength tests were performed with no mouthpiece, with a placebo mouthpiece, and with a MORA mouthpiece. A repeated measures ANOVA showed no significant differences between any of the tests, suggesting that the MORA has no effect on muscular strength.

Orthodontic management of mandibular canine-incisor transposition.

This article presents five cases of an unusual dental anomaly--transposition of mandibular canine and lateral incisor. While every one of the presented cases had its individual characteristics, there are certain common traits. For instance, deciduous canines are usually retained, and the anomaly is found concurrent with other dental problems, such as congenital absence of teeth or peg-shaped lateral incisors. Many transposition cases also have a severe arch length discrepancy, which in itself may be an etiologic factor. In two of our cases orthodontic management included extraction of the transposed lateral incisor, whereas in the remaining three cases teeth were left in their transposed positions. On the basis of the longitudinal records of one of our cases, we speculate that there are early signs of transposition in the making, signs which should be recognized and which could possibly make transposition preventable.

The ectopically erupted mandibular lateral incisor.

Seven cases of ectopically erupting permanent mandibular lateral incisors are reported and their orthodontic management is described. In severely crowded cases the ectopic lateral incisor was extracted. When complete transposition occurred, the teeth were aligned in their transposed positions. If malposition is detected early, orthodontic correction may prevent development of a transposition. Panoramic survey of the developing dentition at the age of 6 to 8 years is a very useful tool in the early detection of this as well as many other dental developmental anomalies.

A biometric study of tooth size and dental crowding.

A study was conducted for the purpose of comparing mesiodistal tooth widths between a group of patients with good tooth alignment and a group of patients with crowded dental arches. Crowded arches were defined as those with more than 4 mm. of space deficiency. The hypothesis tested was whether the arches with more than 4 mm. of crowding consistently had larger teeth than the ones with lesser or no crowding. The difference in sizes between the groups (forty males and forty females) for all teeth measured was found to be statistically significant (p less than 0.001). The multivariate data analysis indicated that the two groups were derived from two different populations and that the maxillary lateral incisors and second premolars and the mandibular canines and premolars were particularly different in these groups. It was also determined that the teeth in males were uniformly larger than in females, but not to a statistically significant level. There was less correlation, however, between the sex and the status of the tooth alignment in dental arches, so that both sexes had similar distribution of crowding versus noncrowding. On the basis of this study of eighty North American Caucasians, it is suggested that one should consider the sum of mesiodistal widths of teeth, in addition to the arch length analysis, in formulating an orthodontic treatment plan. When the cumulative tooth mass of the twenty permanent teeth is 140 mm. or more, the clinician may want to consider extraction therapy for such a case.

An approach to rotational relapse.

The tendency of rotated teeth to relapse after treatment following retention is partially because of the supra-alveolar fibers which are stretched during rotational correction. Early treatment, overrotation, a long retention period, and proper contouring of contact points have been used to reduce relapse. With several surgical methods, it has been shown that releasing the tension in the periodontal fibers by severing the supracrestal and transseptal fibers significantly reduced relapse tendencies following rotation. This study was designed to test a simple surgical method (Vanarsdall) and to examine the effect of transsecting supra-alveolar fibers in orthodontically rotated teeth. Twelve cases in which a tooth and its antimere were rotated in excess of 10 degrees prior to orthodontic treatment were chosen for this study. One of the two rotated teeth was chosen for the gingival fibrotomy, while its antimere was retained by conventional orthodontic means and served as a control. The incision was made at a 45-degree angle to the long axis of the tooth, on the labial and lingual aspects of each tooth, 2 months prior to debanding. A significant decrease in the amount of relapse up to 30 days following removal of appliances in the fibrotomy group as compared to the control group (0.42 degrees and 5.75 degrees, respectively) suggests that the procedure be considered for overcoming rotational relapse.

Variation in morphology of the maxillary central incisors found in class II, division 2 malocclusions.

Class II, Division 2 malocclusions show several common characteristics. One of the features is the presence of a deep overbite ("deckbiss"), which can be the result of an excessive eruption of the maxillary central incisors. This study tested the theory that the deep overbite, together with the apparent entrapment of the mandible, may be partly due to the bending of the maxillary central incisors or the presence of the Collum angle. In a comparison between the group of patients with Class II. Division 2 malocclusions and the control group, it was determined that the former group exhibited significantly larger Collum angles than the latter group (p < 0.005). It is suggested that in describing the maxillary incisor angulation in this type of malocclusion, the long axis of the crown, rather than the long axis of the tooth connecting the incisal edge to the apex, be used as a measure of their position.

A comparison of plain versus multilooped arch wires in stage I of Begg therapy.

In order to overcome the reportedly undesirable side effects of using multilooped arch wires in initial stages of Begg mechanotherapy, a clinical study was conducted in which treatment procedure was modified for the mandibular arch in one group of patients, who received nonlooped or plain mandibular arch wires. This group was closely matched with respect to age, sex, severity of malocclusion, and particularly the amount of anterior mandibular crowding with a group of patients who received multilooped arch wires designed very closely according to the classically prescribed methods. Comparison of the two groups by means of cephalometric measurements of the mandibular incisors at the end of Stage I of treatment demonstrated that the IMPA increased significantly more (p = 0.01) in the multilooped arch wire group. The over-all treatment time was not significantly different in the two groups, although it took longer to resolve the anterior mandibular crowding when plain wires were used. On the basis of this study, it would appear that the use of plain rather than multilooped arch wires in the mandibular arch deserves a favorable consideration in early Begg therapy.

Endodontic-orthodontic management of fractured anterior teeth.

A case history is presented of a 10-year-old patient, who accidentally injured her maxillary central incisor. The fracture of the crown extended 2 mm below the crest of the alveolar bone. After a pulpotomy was done as a temporary measure, orthodontic appliances were placed by bonding brackets on the maxillary anterior teeth and fitting a sectional arch wire to extrude the fractured tooth. After successful extrusion, the fracture line was brought above the level of alveolar bone where successful restoration of the tooth by the acid-etch method could be accomplished.
