Which statement is NOT true regarding ovate pontics and soft tissue development?

Ovate pontics are designed to mimic the natural contours of the gingiva and promote proper soft tissue healing and aesthetics. In this context, the notion that a minimum of 2.5 mm of gingival tissue is needed is not accurate. This figure does not reflect a universally accepted standard for soft tissue development around pontics since successful integration and soft tissue management depend on various factors, including the specific patient's anatomy and the clinical situation. The emphasis in tissue management is more on establishing proper contours and ensuring adequate contact between the pontic and the tissue rather than adhering to a specific measurement.

The other statements are rooted in principles of periodontal health and prosthetic dentistry. Creating a concave pontic receptor site promotes a natural emergence profile and helps in establishing a proper relationship with the surrounding tissues, facilitating optimal aesthetics and hygiene. Considering the preparation of the teeth and the condition of the soft tissues is crucial for ensuring a successful outcome, as both play a significant role in how the pontic will be received and integrated within the oral environment. Additionally, ensuring that the provisional prosthesis contacts the tissue directly allows for better adaptation and tissue shaping during the healing phase, leading to improved aesthetic and functional results once the definitive restoration is placed.
