What is dental freeway space?
What is dental freeway space?
The ‘Freeway space’, interocclusal clearance, is described as the space between the maxillary and mandibular occlusal surfaces when the mandible is in the rest position, and should be 2–4 mm (British Society for the Study of Prosthetic Dentistry, 1996).
How do I increase my freeway space?
Freeway space can be increased by (a) raising the maxillary occlusal plane; (b) lowering the mandibular occlusal plane; or (c) a combination of both. The appearance of the dentures will help determine which of these options to choose.
Why is freeway space important?
It is the primary prerequisite for comfort and optimum function of partial or complete dentures, as it is expressed as a gap that occurs in the vertical dimension separating the position which the mandible assumes in space when it is at rest, and its spatial position when the teeth are brought into contact.
Why we do jaw relation?
Recording jaw relation is very important step during complete denture construction after making final impression and obtaining Master cast. If the jaw relations are incorrect, the dentures will move inorder to occlude with subsequently be dislodged from the ridges during function.
What relaxes jaw muscles?
Massaging your jaw may help increase blood flow and reduce muscle tightness. You can try this by opening your mouth and gently rubbing the muscles next to your ears in a circular motion. This is the area where the temporomandibular joints are located. Try this several times a day, including right before bed.
What is the significance of Interocclusal clearance?
Background and aim: The interocclusal clearance during speech and in mandibular rest position shows an interindividual variation and influences the stability of prosthodontic reconstruction or orthodontic therapy, especially in patients with deep bite or cover-bite.
What’s the average size of a freeway space?
The mean measurements of freeway space in dentate subjects found in this study were within the recommended 2-4 mm range, however, 15% of the subjects in the study had freeway space measurements outside this range. This study would suggest that the range for freeway space measurement could more realistically be 2-7 mm.
Where can I find the determination of freeway space?

How is freeway space measured using dividers and tape?
The divider method involved putting small pieces of tape on the subject’s nose and chin. A small dot was first put on each piece of tape before placement onto the nose and chin, the rest and occlusal face heights were then measured between these two dots using dividers. The freeway space was determined as the Fig. 1.
How to determine freeway space in edentulous individuals?
Aims and Objectives: The aim was to determine freeway space in edentulous individuals by correlating clinical findings of freeway space clinically with the gonial angle cephalometrically. Materials and Methods: The study was conducted on 100 dentulous individuals in the age-group of 20-30 years.
