Pliers and mirrors
Extraction of the VIII° included lower horizontal
in the University of Dentistry
Dr. F. Comella’s Forceps is the only forceps particularly designed for the extraction of the root fragments from the lower horizontal embedded eighths molars. After the crown parting using a bur, the tooth is divided in two parts: mesial and distal.
The mesial part is accessible and easy to remove;
The distal part can instead give some problems because: Positioning in the bone, Retentive root shape, Patient comfort (timing)
The root elevators and other tools currently used can be dangerous in case of accident damaging vases and nerves, particularly the close lingual nerve.
Comella’s forceps has a secure, precise and steady grip ensuring the respect of the surrounding tissue.
The mouth mirror is an indispensable tool for the inspection of the oral cavity, soft tissue, anterior and posterior teeth and for conservative treatment.
To improve these operations the traditional circular shape had been changed with a new “drop shape” able to ensure a better control of the soft tissue, better protection of the tongue wall and a larger view of the superior molar and buccal cavity.
Furthermore, the new “drop shape” design gives more light for a better view in the oral cavity.
Medical History: there are not clinical relevance diseases, the 20 years old patient has two impacted lower third molars that are partially exposed, based on the alveolar nerve and an interesting bacterial stage on both dental crowns with aggravation on distal portion of 37-47 radicular wall. Bacterial infiltration produces exudate, malodorous smell and constant nuisance, caused by inflammatory situation. An avulsion of all four third molars will be done. For lower molars it will be used also the Comella forceps.
>The case: image where it’s possible to see the partial exposure of the crown
>Perform wide edges, in order to have a bigger field of vision
>Demolition of the vestibular area using bone mills, straight handful
>Crown demolition, handful 90 °, the cut has to be tilted distally, straight and deep as much as possible
>Crown Detachment using straight elevator
>Vision for the entire surgical hole
>Root separation (in case of forked roots) with straight handful
>Upper root portion removal with using Comella forceps
>External picture of forceps precise action
>In this image it’s possible to see that the forceps working appropriately leaves the edge of the operating field perfectly intact
>Plastic jaw simulation in order to observe how to perform different surgical steps
>Operating time: 15 minutes. It have been practiced to patience some cortisone injections (Soldesan around the affected area, in order to limit the post-operative bleeding. In the picture it’s possible to glimpse Dr Comella drop shape mirror, very useful and practical especially for retromolar area interventions
The June 13, 2008 was held a course at the State Dentistry University of Milan to students of the first academic year, the theme of the lesson was metal-ceramic preprosthetic preparation in rehabilitations.
Dr. Fabrizio Comella with Prof. Mario Anastasia, Professor of Dental Materials, involved students in interesting but purely technical topics in a simplified way, explaining what dentists daily must face.
