CONSERVATIVE REPLACEMENT FOR POST HEMISECTION MANDIBULAR MOLARS WITH
FIBRE-REINFORCED COMPOSITE RESIN AS AN ADHESIVE BRIDGE: CASE STUDY

Norhayati A, Cheng ZH

Introduction: Recent advances in dentistry has led to a paradigm shift in treatment and
preservation of teeth. Hemisection provides an alternative to extraction and helps saving
a tooth which otherwise would have been removed. It involves removal or separation of a
root along with its accompanying crown portion of two-rooted teeth, most commonly
mandibular molars. It is a suitable treatment option when the non-restorable caries,
resorption, periodontal involvement or perforation is restricted to one root while the other
root is relatively healthy. Case study: We reported two cases of replacement post
hemisection on mandibular molars. The first case was on grossly decayed right mandibular
second molar which successfully treated by endodontic treatment and hemisection was
done on its distal half. The second case was about periodontally affected mesial root of
right mandibular molar. 3-months post hemisection procedure, adhesive bridge
restorations were constructed using fibre-reinforced composite (FRC) resins splinted to the
adjacent premolar and molar. With the evolution of composite resins and development of
fibre-strengthening properties, FRC serves as a good alternative to conventional fixed
prostheses. FRC prostheses offer the advantages of being minimally invasive, less
expensive, good aesthetics, non-corrosive and the ability to bond to the abutment teeth,
thereby compensating for less-than-optimal abutment tooth retention and resistance
form. Conservative management of grossly carious and/or periodontally compromised
multi-rooted teeth not only preserves the dentition but also reduces the financial burden
and occlusal dysfunction associated with tooth loss. Conclusion: These cases highlight that
hemisection of grossly carious and periodontally involved mandibular molar roots followed
by construction of fixed adhesive prostheses with FRC may be a conservative and reliable
treatment option with an acceptable prognosis.
