Introduction: Closing of middle diastema can be challenging aesthetic rehabilitation. The procedures can be more complicated when the cause is not only dental deformity but also caused by frenulum anatomy. Full veneer crown (FVC) is usually the standard solution for closing the diastema, but coronally frenulum can put the result at risk of failure. Methods: This case presents a 21 years old female with middle diastema and coronally penetrating frenulum. After a series of discussion, it was decided to perform frenectomy with V-Y plasty technique before prosthodontic treatment, so it will not give a problem on FVC insertion and black triangle post-FVC insertion. The prosthodontic approach can be challenging because the diastema is too wide to close by two units FVC. The prosthodontist decided to make four units FVC on four anterior teeth subsequently so the dental anatomy could be achieved aesthetically. Results: Healing of frenulum showed the standard height in three weeks post-frenectomy. Making four units FVC and change the dental y-axis, an anatomical standard could be achieved. The patient showed no complaint for a week later. Conclusions: The frenulum anatomy and gap size of middle diastema can be a challenging case. Frenectomy and changing the dental y-axis should be performed in this case to give the patient maximum treatment output.
