“…Metal models with previously mentioned dimensions were embedded in stainless steel flask filled with dental stone to create a mold for packing of acrylic resin Figure (2). The control groups of coldcured acrylic material , vertex and Paladur were cured by an ivomate curing device containing water under air pressure of 30 Pascal for 15 min at 37 ֠ C (18).…”

“…Dental space maintainer is essential in cases of premature loss of primary dentition to prevent malposition, supraeruption , impaction , or crowding of the developing permanent teeth (1). The space maintainer is subjected to force exerted on them when performing various function , therefore , it is important to have good mechanical properties (2).…”

Aim of the study: surface hardness is essential to avoid the indentation or scratch of space maintainer. Efforts have been made to improve the flexible and cold-cured acrylic's strength, by raising the processing temperature, unless the temperature has a chemical impact on the acrylic's qualities. The aim of this study was to study the effect of elevated temperature on the surface hardness of flexible and cold cured acrylic utilized as space maintainer appliance. Methods: Sixty specimens were divided into three groups: flexible acrylic ( Lingchen dental) , cold-cured acrylic (vertex) and (Paladur). Each group was subdivided into two subgroups,10 control and10 experimental . The control group for flexible acrylic was injected at 270 °C ,while for the two types of cold -cure, control groups, the specimens were processed at 37°C . The experimental group for flexible acrylic was injected at 290°C and for the two cold -cure types were processed at 70°C. Hardness was tested by Shore A device for flexible acrylic while for cold -cure specimens, shore D device was used. Results : results showed no significant increase in the hardness of flexible acrylic the mean value of control group is 66.44±0.47 while for experimental group is 66.50±0.48. For vertex and Paladur cold- cured acrylic the surface hardness was increased significantly with increasing processing temperature. The mean values of vertex and Paladur control groups are around 86.14±0.39 and 88.33±0.39 respectively, while for experimental groups are 88.39±0.40 and 88.70±0.25 Conclusion : elevated processing temperature increased the surface hardness of both types of cold acrylic however; the hardness of flexible acrylic was not affected by temperature elevation.

“…Space maintainers are of different types according to the missing teeth,age of the child and indications for each particular case. Some of the Space maintainers used in paediatric dentistry are Band and loop, crown and loop, nance palatal arch, trans-palatal arch, distal shoe and lingual arch space maintainer (Beldiman et al, 2015;Ramakrishnan, Dhanalakshmi and Subramanian, 2019). In this study we are mainly going to see specifically about band and loop space maintainers.…”

Premature loss of teeth in children leads to space loss and affects arch integrity. Space maintainer and space maintenance is an important part of paediatric dentistry as well as a part of interceptive orthodontics. This study aims to determine the prevalence of band and loop space maintainers among children who are 6-10 years old. Data collection was done from going through 86,000 patient records from June 2019 to April 2020. Total sample size was 44 children who were inserted with a band and loop space maintainer. Chisquare test is done to analyse the significance of the study. The analysis showed that the band and loop space maintainer are more prevalent in 6 year old children and mostly done in female children. The reason for tooth loss was due to extensive caries. However, the study showed positive correlation but there was no significance since p=0.276. Use of space maintainers is an important step in interceptive orthodontics and the study concluded that it is more prevalent in 6 year old children.
