INTRAORAL SCANNING
A dental add-on for an electronic communication device including an imager, the dental add-on comprising: a body comprising a distal portion sized and shaped to be at least partially inserted into a human mouth, the distal portion comprising a slider configured to mechanically guide movement of the add-on along a dental arch; and an optical path extending from the imager of the electronic communication device, through the body to the slider, and configured to adapt a FOV of the imager for dental imaging.

24 . A method of dental scanning:
coupling an add-on to a portable electronic device including an imager, said coupling aligning an optical path of said add-on to a FOV of said imager, where said optical path emanates from a distal portion of said add-on which is sized and shaped to be placed within a human mouth;
acquiring, using said imager:
a plurality of narrow range images of one or more dental feature;
at least one wide range image of said one or more dental feature, where said wide range image is acquired from a larger distance from said dental feature than said plurality of narrow range images; and
generating a model of said dental features from said plurality of close range images and said at least one wide range image.
25 . The method of dental scanning according to claim 24 , wherein said plurality of narrow range images and said at least one wide range image are acquired through said add-on.
26 . The method of dental scanning according to claim 24 , wherein said acquiring comprises:
acquiring a plurality of narrow range images through said add-on; and
acquiring at least one wide range image by said portable electronic device.
27 . The method according to claim 24 , wherein said at least one wide range image is acquired through said add-on using an imager FOV which emanates from said add-on distal portion with larger extent than an imager FOV used to acquire said narrow range images.
28 . The method according to claim 24 , wherein said at least one wide range image is acquired using an imager of said electronic device not coupled to said add-on.
29 . The method according to claim 24 , wherein said portable electronic device is an electronic communication device having a screen.
30 . The method according to claim 24 , wherein said model is a 3D model.
31 . The method according to claim 24 , wherein said generating comprises generating a model using said narrow range images and correcting said model using said at least one wide range image.
32 . The method according to claim 24 , wherein said plurality of images are acquired of dental features illuminated with patterned light.
33 . The method according to claim 24 , wherein said add-on optical path transfers patterned light produced by a pattern projector to dental surfaces.
34 . The method according to claim 24 , wherein said at least one wide range image includes dental features not illuminated by patterned light.
35 . A method of dental scanning comprising:
coupling an add-on to a portable electronic device including an imager, said coupling aligning an optical path of said add-on to a FOV of said imager, where said optical path emanates from a distal portion of said add-on which is sized and shaped to be placed within a human mouth;
controlling image data acquired said imager by performing one or more of:
disabling one or more automatic control feature of said electronic device imager; and
determining image processing compensation for said one or more automatic control feature;
acquiring, using said imager, a plurality of images of one or more dental feature;
if imaging processing compensation has been determined, processing said plurality of images according to said processing compensation.
36 . The method according to claim 35 , wherein said automatic control feature is OIS control.
37 . The method according to claim 36 , wherein said determining is by using sensor data used by a processor of said electronic device to determine said OIS control.
38 . The method according to claim 36 , wherein said disabling is by one or more of:
a magnet of said add-on positioned adjacent to said imager; and
software disabling of said OIS control, by software installed on said electronic device.
