The provision of resin-retained bridges (RRBs) on abutment teeth that require composite resin build-ups often proves challenging. This article presents a technique, represented through two clinical cases, that aims to reduce some of the issues associated with such scenarios. It describes the simultaneous cementation of the RRB while also undertaking composite resin additions. It showcases the advantages of such a technique – particularly in terms of maximizing enamel surface area available for bonding to the retainer, and thereby potentially improving the longevity of the prosthesis.
CPD/Clinical Relevance: Careful design and execution is required when providing resin-retained bridgework.

Replacing missing anterior teeth can be particularly demanding where there is a spaced dentition, microdontia or unfavourable contour of potential abutment teeth. A common cause of missing teeth is hypodontia, with figures suggesting that between 0.15% and 16.2% of the population experience the congenital absence of at least one tooth, excluding third molars.1 Variations in reporting criteria and ethnicities may explain this, with Japanese people showing the highest rates and Indians, Black Africans and Aboriginal Australians showing some of the lowest.1
Multidisciplinary orthodontic and restorative management is often required for such cases to idealize the spaces and subsequently facilitate both functional and aesthetic restorative replacement. Orthodontic treatment may not always be able to move teeth into an ‘ideal’ restorative position, resulting in residual/compromised spacing, as demonstrated in Figure 1. Consequently, this requires addressing restoratively, alongside tooth replacement.
