Indication of restoring<unk>  teeth using direct<unk> : #Caries management # Repair fracture of teeth , might be due to trauma #Diastema closure ## Midline diastema are defined as an interdental space greater than 0.5mm within the maxillary central incisors ## Diastema can often considered as<unk>  or malocclusion problem ## Midline diastema often cited from patient as primary<unk>  problem, thus closing them is a commonplace in<unk>  dentistry # Improve<unk>  by changing shape, colour, length and alignment Advantages The advantages are: # Minimally invasive - They require minimal (or no) tooth preparation to enhance resistance and retention form # Significant fewer endodontic complications # Re-intervention is easier as<unk>  are more reversible and amenable to repair # Reduced risk of wear to opposing teeth # Time saving- Only require single appointment # Require no provisional<unk>  # Lower financial cost # Chipping can be repaired by adding new<unk>  layers, and colour changes sometimes can be fixed by<unk>  resin polishing. Longevity Average survival statistic for direct<unk>  is not encouraging. However, there is a lack of conclusive data regarding the longevity of<unk><unk><unk> . However, it has been well established that the more complex the<unk> , the shorter its lifespan. Clinical studies have found that 60 to 80% of all Class III and V<unk>  resin<unk> s remain acceptable after 5 years of clinical service. The main reason for replacement of<unk><unk>  are typically surface discoloration , secondary caries and fracture of<unk> . It is generally accepted that Class IV<unk> s do not last as long as Class III and Class V. One study compared four different<unk><unk><unk>  types over 5 years. Variables assessed included handling characteristics, gingival condition, surface staining, marginal staining, color deterioration, and overall longevity. The Class IV<unk> s had higher failure rates than Class III or V<unk> s. Technique sensitivity Operators should have detailed anatomical knowledge and artistic skill , for example, optimal properties of natural teeth, tooth proportions and their relationships to each other and to the surrounding soft tissues. Operator also must select appropriate restorative materials that match adjacent residual tooth tissue.
