A posterior open bite is a bite relationship where the back teeth do not touch when the jaws close. It usually refers to missing contact between premolars and/or molars on one or both sides. Clinicians use the term in orthodontics, restorative dentistry, and occlusion (how teeth meet) assessments. It can be a temporary finding during treatment or a stable feature of a person’s bite.

An anterior open bite is a bite pattern where the upper and lower front teeth do not touch when the back teeth are together. It is commonly described during dental exams, orthodontic consultations, and speech or chewing assessments. The “open” space is typically visible between the incisors (front teeth) when a person bites down. It can occur from tooth position, jaw growth patterns, or habits and airway-related factors.

open bite is a type of malocclusion where the upper and lower teeth do not touch when the back teeth are together. It most often refers to a gap in the front teeth (anterior open bite), but it can also occur in the back teeth (posterior open bite). Dentists and orthodontists use the term to describe how the bite fits and functions. It is discussed in routine exams, orthodontic consultations, and treatment planning for function and aesthetics.

A deep bite is a type of bite relationship where the upper front teeth overlap the lower front teeth more than is typical. It is discussed in general dentistry, orthodontics, and prosthodontics because it can affect function, comfort, and tooth wear. Clinicians may describe deep bite in terms of **vertical overlap** (how much the top incisors cover the lower incisors). It can occur due to tooth position, jaw growth patterns, or a combination of both.

overbite is the vertical overlap of the upper front teeth over the lower front teeth when you bite together. It is a normal occlusal (bite) feature, but it can be increased (deep) or reduced (edge-to-edge or open bite). Dentists and orthodontists use the term overbite to describe bite relationships and plan care. It is commonly discussed in routine exams, orthodontic consultations, and restorative treatment planning.

overjet is the horizontal distance between the upper front teeth and the lower front teeth when the back teeth are together. It describes how far the upper incisors sit in front of the lower incisors. Clinicians use overjet as a standard measurement in orthodontics, restorative planning, and bite (occlusion) assessment. It is recorded during dental exams to document tooth position and how it changes over time.

Angle classification is a dental system for describing how the upper and lower teeth fit together (the bite). It is most commonly based on the relationship of the permanent first molars, and sometimes the canines. Dentists and orthodontists use it to label common bite patterns as Class I, Class II, or Class III. It is a communication tool used in exams, records, referrals, and treatment planning discussions.

Class III malocclusion is a bite relationship where the lower teeth sit ahead of the upper teeth when the jaws are closed. It is commonly described as an “underbite,” and it may involve the front teeth, the back teeth, or both. Clinicians use the term to document diagnosis, communicate findings, and plan orthodontic and surgical care. It is most often discussed in orthodontics, pediatric dentistry, and oral and maxillofacial surgery.

Class II malocclusion is a common way dentists and orthodontists describe a bite where the upper teeth/jaw sit relatively forward compared with the lower teeth/jaw. In plain terms, it often looks like an “overbite/overjet” pattern, where upper front teeth may appear ahead of the lowers. It is most commonly used in orthodontic exams, dental records, and treatment planning discussions. It is a diagnostic classification, not a material or a procedure by itself.

Class I malocclusion is an orthodontic way to describe how the upper and lower teeth fit together. It means the back teeth (especially the first molars) have a “normal” front-to-back relationship, but the teeth may still be crooked or misaligned. It is commonly used in dental charts, orthodontic consultations, and treatment planning discussions. It helps clinicians describe a bite pattern in a consistent, standardized way.
