ABSTRACT A hybrid expander is a newly designed bone-anchored expander consisting of 2 mini-screws and palatal acrylic; it does not cover any teeth. The aim of this case report is to present the treatment of a patient with transversal maxillary deficiency by hybrid expander. An 11.4-year-old female patient came to our clinic complaining about the appearance of her teeth. She had a narrow maxillary arch, unilateral dental crossbite, anterior dental crowding, and dental Class II canine and molar… 


Application and effectiveness of a mini-implant- and tooth-borne rapid palatal expansion device: the hybrid hyrax.
The hybrid hyrax with a face mask for maxillary protraction appears to be effective in minimizing mesial migration of the dentition and can be employed especially in patients with reduced anterior dental anchorage.

After RPE, significant increases in the transverse dimensions of the nasal cavity, the maxillary basal bone, and the midpalatal suture opening occurred, with the greatest increase in the mid Palaeolithic suture followed by basal bone and nasal cavity.
Nonsurgical rapid maxillary alveolar expansion in adults: a clinical evaluation.
RMAE is an acceptable alternative to SA-RME in adults for most cases of maxillary transarch deficiency and is defined as rapid maxillary alveolar expansion (RMAM), followed by a commentary and response.
The Rotterdam Palatal Distractor: introduction of the new bone-borne device and report of the pilot study.
A new bone-borne palatal distractor has been developed that automatically stabilizes the device and no screw fixation is necessary anymore, and the data of five acquired deformity and eight congenital deformity patients that were treated with this distractor are reported.
Effects of a modified acrylic bonded rapid maxillary expansion appliance and vertical chin cap on dentofacial structures.
It is concluded that the vertical chin cap is an effective appliance for preventing the adverse vertical effects of RME in patients with a crossbite and a vertical growth pattern.

Although posterior crossbite was corrected in a fairly short period of time, the quad helix appliance caused considerable buccal tipping of the maxillary first permanent molars.
Three-dimensional evaluation of hybrid expander appliances: A pilot study.
The hybrid expander, minimally invasive expansion appliance that protects teeth by including bone support, can be used easily for rapid maxillary expansion treatment, using cone-beam computed tomography (CBCT).
Parameters Affecting Primary Stability of Orthodontic Mini-implants
Compacta thickness, implant design and implant site preparation have a strong impact on the primary stability of mini-implants for orthodontic anchorage: Depending on the insertion site and local bone quality, the clinician should choose an optimum combination of implant and pilot drilling diameter and depth.

From this evidence, it would seem that rapid maxillary expansion will separate the palatine bones and splay outward the pterygoid processes of the sphenoid bone.
Short-term treatment effects of quad-helix on maxillomandibular expansion in patients with maxillary incisor crowding
The quad-helix treatment gives rise to spontaneous expansion of the mandibular arch concurrent withmaxillary expansion in the early mixed dentition patients with maxillary incisor crowding, which could turn molar occlusal relationships for the better from Class II to Class I.
