Abstract
Objective: To compare the clinical efficacy of Ghana Shyam's TEFF space maintainer with band and loop space maintainer. Material and Methods: This split-mouth randomized clinical trial was conducted on 20 children (7-9 years), requiring bilateral/contralateral space maintenance therapy. After consent, all the selected children received both space maintainers and were followed up periodically every six months up to two years for clinical assessment according to the evaluation protocol. Instructions and motivation were given to the children. OHI (S) index was recorded before cementation of appliances. The following aspects were analyzed: 1) efficiency and function; 2) dislodgement due to cement loss; 3) breakage at soldered parts; 4) carious or gingival inflammation affecting abutment teeth; 5) distortion of band; 6) being embedded in gingival tissues / gingival slopping; and 7) initial and final S-OHIS scores. Statistical analysis was done using Fisher exact test for survival time and Chi-square test for chewing efficiency. Results: At 24th-month follow-up, 14 Ghana Shyam's TEFF space maintainers and 16 band and loop space maintainers were found to be intact. Conclusion: As both space maintainers demonstrated similar mean survival time Ghana Shyam's TEFF space maintainer with the added advantage of being functional can be recommended as an effective alternative to band and loop in premature loss of primary molar clinical situations.

Primary teeth are determining factors in the development of occlusion
At 24th-month follow-up, 14 Ghana Shyam's TEFF space maintainers and 16 band and loop space maintainers were found to be intact. As both space maintainers demonstrated similar mean survival time Ghana Shyam's TEFF space maintainer with the added advantage of being functional can be recommended as an effective alternative to band and loop in premature loss of primary molar clinical situations
The effects of the premature loss of primary teeth include decreased arch length, crowding, crossbite in the first permanent molar area, reduced masticatory function and accumulation of plaque material and food debris, which will often result in increased dental caries activity and gingival inflammation [1]
Summary
The effects of the premature loss of primary teeth include decreased arch length, crowding, crossbite in the first permanent molar area, reduced masticatory function and accumulation of plaque material and food debris, which will often result in increased dental caries activity and gingival inflammation [1]. If nature's best space maintainer is lost prematurely, appliance selection depends on factors associated with each case regarding the child age, child cooperation as well as the parents’ desire of having fixed or removable replacement. Among preferable alternative fixed space maintainers, band and loop space maintainer is one of the most frequently used appliance and it was found to have survival times significantly greater than bilateral space maintainers such as the mandibular arch and Nance appliance [3]. It was previously reported that the band and loop space maintainers lasted the longest with a mean survival time of 13 months [5]
