What is an anatomical landmark of the maxilla?
The maxilla is the upper dental arch that contains the maxillary alveolar process, the maxillary teeth and the maxillary sinuses. It sits on either side of the nasal cavity and below the orbits.
What is an anatomical landmark on the mandible?
The landmarks include the mandibular foramen, the inferior alveolar nerve, the mental foramen, the mental nerve, the lingual nerve, the incisive canal and the incisive nerve all of which are of particular interest to clinicians who are planning dental implant surgery.
What is anatomical landmarks in dentistry?
Landmarks of the oral tissues include the palate, tongue, cheeks and floor of the mouth. It is significant to recognize the normal appearance of these structures during an intraoral examination of the patient.
What are the anatomical landmarks of the body?
Body Landmarks
- Abdominal – anterior body trunk inferior to ribs.
- Acromial – point of shoulder.
- Antecubital – anterior surface of elbow.
- Axillary – armpit.
- Brachial – arm.
- Buccal – cheek area.
- Carpal – wrist.
- Cervical – neck region.
Which bony landmark is found on the maxilla and mandible?
The teeth are positioned in the dental arches, which are located in both the maxilla and mandible bones.
Which of the following landmarks are located by the midline of the mandible?
Genial tubercle – The genial tubercle is a spiny protuberance or prominence (sometimes two) of bone located in the midline on the lingual aspect of the mandible below the roots of the incisor teeth.
Why are anatomical landmarks important?
Summary. Early anatomic landmarks and their normal appearance on ultrasound serve as the basis for understanding normal fetal development as a function of gestational age and their pathologic conditions, which in a combined fashion will ultimately reflect on management (see Chapter 12).
What anatomical landmark is found on the nasal or medial surface of the body of maxilla?
Viewed medially, the maxillary sinus is evident with its medially facing ostium. It articulates with the palatine bone posteriorly and with the ethmoid, lacrimal, and inferior concha bones medially.
Why anatomical landmarks play a big role in dentistry?
The landmarks of an edentulous jaw are grouped into limiting structures, supporting structures and relief area. These are the sites that will guide us in having an optimum extension of the denture so as to engage maximum surface area without encroaching upon the muscle actions.
Why is it important to know the landmarks of the face and oral cavity?
It is important for the dental team to know the appearance of normal anatomy of the face and oral cavity. This knowledge provides a sound basis for identifying abnormal conditions.
What are some anatomical landmarks of bones?

What bony landmarks does the maxilla articulate with?
[3] The maxilla connects with surrounding facial structures through four processes: alveolar, frontal, zygomatic and palatine. It articulates superiorly with the frontal bone, the zygomatic bone laterally, palatine bone posteriorly and with the upper teeth through the alveolar process inferiorly.
What are the landmarks in maxilla and mandible for complete denture fabrication?
Anatomical Landmarks in Maxilla and Mandible for Complete Denture Fabrication 1 Incisive papilla 2 Mid palatine raphe 3 Cuspid eminence 4 Fovea palatinea More
What is the difference between a mandible and a maxilla?
THE TOTAL AREA OF SUPPORT FROM THE MANDIBLE IS SIGNIFICANTLY LESS THAN FROM THE MAXILLA. THE AVERAGE AVAILABLE DENTURE BEARING AREA FOR AN EDENTULOUS MANDIBLE IS 14cm2 , WHEREAS FOR EDENTULOS MAXILLA IT IS 24cm2. THEREFORE THE MANDIBLE IS LESS CAPABLE OF RESISTING OCCLUSAL FORCES THAN THE MAXILLA.
What are the anatomic landmarks present in a maxillary arch?
In a Maxillary Arch, following anatomic Landmarks are present; Incisive Papilla: It is a pad of fibrous connective tissue overlying the orifice of the nasopalatine canal. Significance:Stable landmark and gives its relation to incisive foramen through which the neurovascular bundle emerge and lie on the surface of bone.
What is the function of the maxilla in the skull?
The Maxilla. The maxilla, also known as the upper jaw, is a vital structure of the viscerocranium. It is involved in the formation of the orbit, nose and palate, holds the upper teeth and plays an important role for mastication and communication.
