Methods Of Achieving Haemostasis During FinalImpression Making For Tooth Supported Full MouthRehabilitation Treatment: A Retrospective Study
European Journal of Molecular & Clinical Medicine,
2020, Volume 7, Issue 1, Pages 3250-3259
Recording of final impression is one the most important procedures in tooth supported full mouth rehabilitation [FMR] treatment. Accurate impression ensures accurate fitting of prosthesis. Accurate fitting can be achieved only if tooth margins are clearly recorded. Retraction of the gingiva can cause the gingival tissues to bleed. Bleeding will in turn cause contamination of the tooth preparation zone and can lead to voids being incorporated into the impression. This study describes the various haemostatic agents that have been used while taking the final impression in FMR cases.
Aim: To evaluate the methods and techniques used to achieve haemostasis while recording final impression of tooth supported FMR cases.
Materials and Methods
This study was designed as a retrospective study. Data for the study was obtained by analysing the patient records of 86000 patients that have been treated from June 2019 to March 2020. Haemostatic techniques were used in 69 cases while recording the final impression. Descriptive statistics were used to get the frequency percentage of the different methods used for achieving haemostasis during impression making. SPSS version 20 was
used to carry out statistical analysis. Chi square test was used to find a correlation between age and type of haemostatic method used.
In 27.5% of cases aluminium chloride was used whereas in 43% of cases ferric sulphate was used. In 68.8% cases no haemostatic agent was used. There was no significant correlation between age and the type of haemostatic method used, P value obtained was 0.069. There was no significant correlation between gender and type of haemostatic method used, P value obtained was 0.420.
Most of the FMR impressions cases did not involve the use of any haemostatic agents. Aluminium chloride was used in a few cases followed by ferric sulphate. There was no correlation found between age, gender and type of haemostatic method used.
