These heads are to be attached onto the Munchies® Vibe.
This pack of two heads includes one anterior nodular attachment and one posterior nodular attachment head.
The posterior nodular attachment engages all premolar and molar teeth, regardless of the occlusal plane. This is critical for success in engaging all teeth simultaneously, a feature which other flat plane acceleration devices cannot provide.
The anterior nodular attachment engages all maxillary and mandibular anterior teeth, regardless of the overbite and uneven incisal planes.
