Banding versus bonding of first permanent molars: a multi-centre randomized controlled trial

A 21-year-old female came with a chief complaint of irregularly placed teeth in the upper and the lower front region. She had no medical and dental history. Her intra oral examination revealed mild crowding in relation to upper and lower anteriors and an increased overbite [Table/ Fig-1,2]. She was decided to be treated by a nonextraction approach with a fixed appliance (M.B.T .022 slot). The bonding of the second molars with the " Express prepared buccal tube bonding technique" was carried out because of inability to band the left second mandibular molar and frequent debonding of buccal tubes. We employed this bonding technique to correct the buccal occlusion and establish " Andrews first key to occlusion that is intra arch alignment.Both the mandibular 2nd molars were bonded using this custom technique for a better bond strength and to provide maximum resistance against being dislodged by the force of a higher dimension stainless steel wire as it is a requisite for levelling.The increased surface area and adherence to anatomic details effect the bonding strength of the buccal tubes and ensure minimal breakage due to torsional stress.

Banding on Adolescents: Is Molar Band Height Different than Clinical Crown Height?

et al. 2014

Introduction: Bonding of the teeth with brackets have eased the orthodontic procedure. However the bonding of molars is not very successful because of the occlusal force, difficulty in moisture control and age factor. Banding is usually the safe option which is again associated with gingival problems. Objective:To compare the molar band height with that of adolescent maxillary molar height. Materials & Method:A total of 33 maxillary adolescent casts and 30 average sized molar bands were retrieved from the orthodontic clinic of Kathmandu University Hospital. The height of the tooth as well as molar band were measured at 4 different points: mesio-buccal (MB), disto-buccal (DB), mesio-palatal (MP), disto-palatal (DP) and compared with independent t-test by SPSS software. p-value was kept at 0.01 for significance. Result:There is no any statistical significant difference between the tooth and band heights at MB, DB and DP points. The difference is found on only one point MP which is statistically significant. Conclusion:There is a need of separate molar bands for adolescent patients. The band dimension should be reduced occlusocervically to avoid gingival impingement.

“…Despite the advantages in terms of comfort, minor periodontal damage 3 and shorter chair time, direct bonding of molars is not yet universally accepted among orthodontists. Randomized clinical trials 2,6 validated by a systematic review 7 have shown that failure of tubes bonded to molars is considerably higher than molars banded with glass ionomer cement. However, the vast majority of patients in these studies consisted of children and adolescents.…”

Survival analysis of banding and bonding molar tubes in adult patients over a 12-month period: a split-mouth randomized clinical trial

et al. 2016

This split-mouth randomized clinical trial aimed to compare the survival rate of bonding and banding molar tubes in adult orthodontic patients. Eligibility criteria included adults (aged >18 years), no active caries, restorations, or fractures in the upper and lower molars. The main outcome was any type of first-time failure in molar tubes. A computer-generated randomization scheme was used in a 1:1 ratio. The survival rate was estimated for 32 adult patients, in whom a tube was bonded to a molar tooth using composite resin on one side and a band was cemented with glass ionomer onto the same tooth in the contralateral arch. A total of 59 banded and 59 bonded molars were followed up for 12 months. Blinding was not applicable. Survival analysis including Cox regression was used at p < 0.05. The survival rate of bonded molars was not statistically different from that of banded molars (log-rank test, p = 0.97). Hazard ratio (HR) was 0.72 (95%CI, 0.38-1.31). Bonded upper molars yielded a survival rate of 81.25% (26 out of 32) compared to 71.87% (23 out of 32) for banded upper molars. The survival rate was 66.66% (18 out of 27) for banded lower molars and 59.25% for bonded lower molars (16 out of 27). The HR for lower vs. upper arch was 2.16 (95%CI, 1.18-3.98). No serious problem was observed other than gingivitis associated with plaque accumulation. In contrast to previous studies in young patients, in adults, bonding orthodontic tubes to molars is similar to molar banding. However, both procedures had a high failure rate in the lower arch.
